If we characteristic as a lot as expend away from a expansive catastrophe, we dwell on the early beginnings of human history
The point of this newsletter is no longer to foretell how many participants will ever dwell.
What I learned from writing this put up is that our future is doubtlessly very, very gigantic. Here is what I strive to affirm here.
If we expend every various marvelous – and provide protection to ourselves from the dangers that nature and we ourselves pose – we’re most entertaining initially of human history.
Before we ask ahead, let’s ask lend a hand. How many came sooner than us? How many participants maintain ever lived?

add advertising hereIt’s no longer that you might possibly presumably judge to reply to this query exactly, however demographers Toshiko Kaneda and Carl Haub maintain tackled the query the tell of the historical data that we develop maintain.
There isn’t a explicit 2nd in which humanity came into existence, as the transition from species to species is slack. Nonetheless if one wants to depend all participants one has to achieve a probability about when the first participants lived. The 2 demographers extinct 200,000 years sooner than recently as this cutoff.1
The demographers estimate that in these 200,000 years about 109 billion other folk maintain lived and died.2
It’s miles these 109 billion other folk we want to thank for the civilization that we dwell in. The languages we sigh, the meals we put collectively dinner, the music we revel in, the instruments we tell – what we all know we learned from them. The properties we dwell in, the infrastructure we depend on, the massive achievements of structure – essential of what we gaze around us became as soon as built by them.
In 2022 7.95 billion of us are alive. Taken along with these that maintain died, about 117 billion participants were born since the daybreak of as a lot as the moment humankind.
This suggests that these of us who’re alive now signify about 6.8% of all other folk that ever lived.
These numbers are arduous to web. I tried to affirm it correct into a visualization to envision them into standpoint.3
It’s a expansive hourglass. Nonetheless as a change of measuring the passage of time, it measures the passage of different folk.
Every grain of sand here represents 10 million other folk: every three hundred and sixty five days 140 million infants are born. So we add 14 grains of sand to the hourglass. Every three hundred and sixty five days, 60 million other folk die; this formulation 6 grains roam thru the hourglass and are added to the expansive want of different folk that maintain died.4

How many participants will most likely be born sooner or later?
We don’t know.
Nonetheless we all know one ingredient: The future is large, the universe will exist for trillions of years.
We are in a position to tell this reality to gain a sense of how many descendants we would want in that sizable future ahead.
The need of future other folk is determined by the scale of the inhabitants at any time limit and the most effective scheme long every of them will dwell. Nonetheless the biggest ingredient will most likely be how long humanity will exist.
Before we ask at a differ of very various most likely futures, let’s open with a easy baseline.
We are mammals. One formulation to evaluate how long we would live to boom the tale is to envision a question to how long various mammals live to boom the tale. It looks that the lifespan of a typical mammalian species is set 1 million years.5 Let’s judge a few future in which humanity exists for 1 million years: 200,000 years are already in the lend a hand of us, so there would be 800,000 years restful ahead.
Let’s opt into consideration a location in which the inhabitants stabilizes at 11 billion other folk (according to the UN projections for the pause of this century) and in which the realistic existence dimension rises to 88 years.6
In one of these future, there would be 100 trillion other folk alive over the next 800,000 years.
The chart visualizes this. Every triangle represents 7.95 billion other folk – it is the green triangle form from the hourglass above and corresponds to the need of us alive recently.
Every row represents the birth of half of a thousand billion younger other folk. For 100 trillion births there are 200 rows.
At the same time as you happen to disagree with the numbers I tell in my location it is straight forward for you to perceive how various numbers would consequence in various futures. Here are two examples:
- At the same time as you happen to evaluate the realm inhabitants will stabilize at a level that’s 50% elevated than in my calculation, then the need of future births will most likely be 50% elevated. The chart would be 50% wider. It might possibly possibly possibly relate the births of 150 trillion younger other folk.
- At the same time as you happen to evaluate the realm inhabitants can maintain a dimension of correct a thousand million other folk, then the chart would be most entertaining an eleventh as huge and would relate 9.1 trillion births.7
The chart exhibits how many younger other folk might possibly possibly be born in the next 800,000 years, a future in which participants live to boom the tale for thus long as a typical mammalian species.
Nonetheless, in spite of all the pieces, humanity is one thing else however “a typical mammalian species.”
One ingredient that sets us aside is that we now – and here’s a most up-to-date pattern – maintain the skill to abolish ourselves. Since the advance of nuclear weapons, it is in our energy to ruin all of us who’re alive and motive the pause of human history.
Nonetheless we’re furthermore various from all various animals in that we maintain the probability to present protection to ourselves, even in opposition to essentially the most low risks. The unhappy dinosaurs had no protection in opposition to the asteroid that wiped them out. We develop. We already maintain efficient and properly-funded asteroid-monitoring programs and, in case it turns into mandatory, we might possibly possibly be ready to deploy technology that protects us from an incoming asteroid. The pattern of unparalleled technology gives us the probability to live to boom the tale for for essential longer than a typical mammalian species.
Our planet might possibly possibly remain liveable for roughly a thousand million years.8 If we live to boom the tale as long as the Earth stays liveable, and according to the placement above, this might possibly be a future in which 125 quadrillion younger other folk will most likely be born. A quadrillion is a 1 followed by 15 zeros: 1,000,000,000,000,000.
A thousand million years is a thousand times longer than the million years depicted on this chart. Even very slack spirited changes will fully remodel our planet over one of these long stretch of time: a thousand million years is a timespan in which the realm will roam thru rather a lot of supercontinent cycles – the realm’s continents will collide and waft aside repeatedly; original mountain ranges will possess after which erode, the oceans we’re acutely aware of will depart and original ones inaugurate up.
Nonetheless if we provide protection to ourselves properly and safe homes past Earth, the future might possibly possibly be essential greater restful.
The solar will exist for but every other 5 billion years.9 If we pause alive for all this time, and according to the placement above, this might possibly be a future in which 625 quadrillion younger other folk will most likely be born.
How will we agree with a quantity as expansive as 625 quadrillion? We are in a position to gain lend a hand to our sand metaphor from the first chart.
We are in a position to agree with recently’s world inhabitants as a patch of sand on a seaside. It’s a small patch of sand that barely qualifies as a seaside, correct expansive sufficient for a single person to sit down down down. One sq. meter.
If the original world inhabitants were represented by a small seaside of one sq. meter, then 625 quadrillion other folk would possess up a seaside that is 17 meters huge and 4600 kilometers long. A seaside that stretches all across the US, from the Atlantic to the Pacific cruise.10
And participants might possibly possibly live to boom the tale for even longer.
What this future might possibly possibly ask take care of is arduous to agree with. True as it became as soon as arduous to agree with, even slightly lately, what recently might possibly possibly ask take care of. “This original 2nd extinct to be the inconceivable future,” as Stewart Payment set up it.

A catastrophe that ends human history would abolish the sizable future that humanity would in every other case maintain.
And it’d be horrific for these which can be alive on the 2nd.
The participants that dwell then will most likely be correct as proper as you or me. They’ll exist, they correct don’t exist but. They’ll feel the solar on their pores and skin and they are able to revel in a swim in the ocean. They’ll maintain the the same hopes, they are able to feel the the same pain.
‘Longtermism’ is the foundation that other folk that dwell sooner or later topic morally correct as essential as these of us who’re alive recently.11 When we set up a question to ourselves what we must develop to achieve the realm a bigger state, a longtermist would not most entertaining opt into consideration what we will give you the option to develop to reduction these around us factual now, however furthermore what we will give you the option to develop for these that near after us. The primary point of this newsletter – that humanity’s most likely future is sizable – matters vastly to longtermists. The vital correct query of longtermism is ‘what will we develop to crimson meat up the realm’s long-duration of time possibilities?’.
In many ways many participants are already longtermists. The accountability we maintain for future generations is why so many work to lower the dangers from local weather switch and environmental destruction.
Nonetheless in various ways we pay most entertaining small consideration to future risks. In the the same formulation that we work to lower the dangers from local weather switch, we must listen to a essential broader differ of doubtlessly even greater risks and lower them.
I’m with out a doubt petrified of these catastrophic and existential risks.12 Besides to nuclear weapons, there are two various primary risks that wretchedness me vastly: Pandemics, critically from engineered pathogens, and synthetic intelligence technology. These technologies might possibly possibly consequence in expansive catastrophes, either by somebody the tell of them as weapons or even unintentionally as the of accidents.13
Huge risks are no longer most entertaining a field sooner or later — they are a actuality now
We don’t want to evaluate other folk that dwell billions of years sooner or later to perceive our responsibilities. The bulk of recently’s younger other folk can set up a question to to perceive the next century. Some of our grandchildren might possibly possibly dwell long sufficient to perceive the 23rd century. A catastrophe in the next decades would be horrific for fogeys very end to us.
The point of interest of this newsletter is the long-duration of time future, however this shouldn’t give the affect that the dangers we’re facing are confined to the future. A whole lot of expansive risks that might possibly consequence in unparalleled mess ups are already with us now. Utilizing the nuclear weapons that exist at this 2nd would ruin millions straight and billions in the ‘nuclear winter’ that follows (gaze my put up on nuclear weapons). No longer sufficient other folk maintain registered how the placement we’re in has modified. AI capabilities and biotechnology maintain developed all in an instant and are no longer any longer science fiction; they’re posing risks to these of us who’re alive recently.14
Similarly this newsletter focuses largely on the inability of human lives, however there would be various losses too: nuclear battle would devastate nature and the realm’s flowers and fauna; existential catastrophes would abolish our custom, our civilization.
The point is that even when we most entertaining opt into consideration the impact of these risks on the original period and most entertaining opt into consideration the skill lack of lives, they’re among essentially the most urgent complications with our time. Here is essential extra the case if we opt into consideration their impact past mortality and their impact on future generations.
The reduction of existential risks is one of the biggest duties of our time, but this might possibly possibly be very no longer current
The original pandemic has made it sure how badly the realm has no longer current pandemic preparedness. This illustrates a extra total point. By lowering the probability of the catastrophes which would endanger our entire future – as an instance the very worst that you might possibly presumably judge pandemics – we would furthermore lower the probability of smaller, but restful terrible, mess ups, akin to COVID-19.
As a society we spend most entertaining small consideration, cash, and energy on the dangers that imperil our future. Few of us are longtermists. Simplest very few are even enraged by these risks, when in actuality these are complications that desires to be central to our custom. The unparalleled energy of recently’s technology requires unparalleled accountability.
Technological pattern made the excessive dwelling standards of our time that you might possibly presumably judge. I judge that a substantial share of the fruits from this development desires to be spent on lowering the dangers and detrimental penalties from explicit technologies.
Extra researchers desires to be ready to leer these risks and the most effective scheme we will give you the option to lower them. I’d love to perceive extra artists who affirm the importance of the sizable future in their work. And crucially I judge it desires competent political work. I agree with that sooner or later international locations can maintain ministries for the reduction of catastrophic and existential risks and one of the vital realm’s most important institutions will most likely be dedicated to the a long way-sighted work that protects humanity.
This would possibly be too gradual to react as soon as the worst has came about. This suggests we want to be proactive; we want to perceive the threats now.
The original location in which these risks are no longer frequently receiving any consideration is provoking and depressing. Nonetheless it is furthermore a expansive opportunity. On story of these risks are so very no longer current, a occupation dedicated to the reduction of these risks is most likely among the acceptable alternatives that you furthermore mght can fair maintain got while it is main to want to achieve the realm a bigger state.
Up to now I’ve most entertaining spoken about the dangers that we face. Nonetheless our expansive future formulation that there are expansive alternatives too.
Concerns are solvable. Here is for me the biggest perception that I learned from writing Our World in Recordsdata over the final decade.
When compared to the sizable future ahead, the 2 centuries shown on this chart listed below are most entertaining a posthaste episode of human history. Nonetheless even in one of these brief duration we maintain made huge growth in opposition to many expansive complications.
Given sufficient time we will give you the option to pause the horrors of recently. Poverty is no longer inevitable; we will give you the option to attain a future the assign other folk are no longer stricken by scarcity, a world with out want or want. Ailments that are incurable recently might possibly possibly be curable in fair a few generations; we already maintain a terrific observe file in bettering other folk’s health. And we will give you the option to attain a world in which we give up adverse the ambiance and attain a future in which the realm’s flowers and fauna flourishes.
Our younger other folk and grandchildren can proceed the growth we’re making, and they would possibly also fair compose artwork and compose a society extra beautiful than we will give you the option to even agree with.

The point of this newsletter became as soon as to perceive that the future is gigantic. If we expend every various marvelous the sizable majority of participants that might possibly ever dwell will dwell sooner or later.
And this requires us to be extra cautious and considerate than we’re now. True as we ask lend a hand to the heroes who finished what we revel in recently, these that near after us will most likely be acutely aware what we did for them. We might possibly be the ancestors of a extremely expansive want of different folk. Let’s possess obvious we’re valid ancestors.
For this we want to opt the dangers we’re facing extra critically. The hazards we’re already facing are excessive. Giving this actuality the dignity it deserves is step one, and most entertaining very few maintain taken it. The following step will most likely be to name what we will give you the option to develop to lower these risks, after which characteristic about doing that.
Let’s furthermore gaze the chance that we maintain. Those that came sooner than us left us a essential greater world; we will give you the option to develop the the same for the a expansive want of who near after us.
Pointers on what to learn on our long-rush future and the probability of existential catastrophes
There are some elegant books and sources:
- For a substantial overview on existential risks and the most effective scheme we will give you the option to lower them I like to recommend Toby Ord’s out of the ordinary guide ‘The Precipice’. It’s miles one of the biggest books I in actual fact maintain learn.
- On the dangers and alternatives of synthetic intelligence, I like to recommend Brian Christian’s guide ‘The Alignment Project – Machine Studying and Human Values’.
- The overview crew of the non-earnings “80,000 Hours” focuses on the query of what you might possibly presumably develop with your occupation to achieve the realm a bigger state, the reduction of expansive risks is one of their key solutions. A starting up point on existential risk reduction is this overview written by Benjamin Todd.
- Two ‘field profiles’ on risks that are on the 2nd on many participants’s minds are:
- The profile on ‘Reducing world catastrophic biological risks’ written by Gregory Lewis.
- And the profile on Impolite Dangers from Climate Alternate authored by Roman Duda and Arden Koehler.
- Two ‘field profiles’ on risks that are on the 2nd on many participants’s minds are:
- In August this three hundred and sixty five days Will MacAskill will submit his original guide ‘What We Owe The Future’. His manuscript very essential inspired this put up and I very essential recommend his guide. It has modified how I judge about my time on Earth.
Acknowledgements: I’d take care of to thank Charlie Giattino, Esteban Ortiz-Ospina, Anders Sandberg, Edouard Mathieu, Hannah Ritchie, and Will MacAskill for his or her very sensible comments to this essay.
The future will no longer correct happen to us, it is us who compose the realm we will give you the option to dwell in. Isaac Asimov saw it take care of this: 15
“There are no longer any catastrophes that loom sooner than us which can’t be refrained from; there is nothing that threatens us with drawing end destruction in one of these fashion that we’re helpless to develop one thing about it. If we behave rationally and humanely; if we focus coolly on the complications that face all of humanity, in preference to emotionally on such nineteenth century matters as national security and native delight; if we seek for that it is not one’s neighbors who’re the enemy, however hassle, lack of understanding, and the cool indifference of pure law—then we will give you the option to resolve the entire complications that face us. We are in a position to deliberately dangle to develop no longer maintain any catastrophes the least bit.” – Isaac Asimov

Appendix to ‘The Future is Huge’
My predominant files provide is the long-rush estimate by demographers Toshiko Kaneda and Carl Haub (reference under).
From 200,000 BCE till 2020 they calculate that 116,761,402,413 other folk were born. 7,772,850,162 of these other folk were alive in 2020.
Pointless to claim the error margins around both of these numbers – critically the historical one – are expansive, which Kaneda and Haub clearly acknowledge. I’m no longer the tell of their point estimates – neither in the text nor in the chart – because I judge that these estimates, all the most effective scheme down to the particular person person, would counsel a corrupt sense of precision.
Older estimates of how many participants maintain ever lived were printed by Goldberg (1983) and Deevey (1960). They arrived at lower estimates – of 55 billion and 81 billion respectively. Beforehand it became as soon as belief that as a lot as the moment participants emerged most entertaining essential later and earlier estimates assumed greater health conditions, i.e. lower mortality, of different folk in the a long way-off past.
I judge the extra most up-to-date work by Kaneda and Haub is the acceptable estimate that is accessible. Nonetheless the expansive uncertainties and the massive series of various estimates that were printed in most up-to-date decades desires to be emphasised.

My replace of Kaneda and Haub:
Kaneda and Haub printed estimates as a lot as mid-2020.
I updated the figures from Kaneda and Haub for mid-2022 by adding the births in the next 2 years. Fixed with the UN there were 139,975,303 births in 2020 and 139,821,086 births in 2021 (these were estimates printed sooner than the pandemic and are no longer proper observations, however the imprecision of these estimates is small relative to the expansive uncertainties in the different relevant figures).
This suggests the entire want of different folk ever born as a lot as 2022 is 116,761,402,413 + 139,975,303+139,821,086=117,041,198,802 births
Fixed with the UN 7,953,952,577 other folk are alive in 2022.
Folks that died between 200,000 BCE and 2022: 116,921,736,195 – 7,953,952,577=108,967,783,618 deaths
Fragment of different folk alive recently among all other folk ever born: (7,953,952,577 / 117,041,198,802) 100=6.8%
Calculations for drawing the hourglass visualization: Humanity’s past and original in grains of sand
Every grain of sand represents 10 million other folk.
Grains to suggest recently’s inhabitants: 7,953,952,577 / 10,000,000=795 grains
Grains to suggest the tiresome: 108,967,783,618/ 10,000,000=10,897 grains (to no longer counsel a misguided sense of sure wager around this quantity I rounded it to 10,900 grains in the visualization).
The location shown in the chart on humanity’s most likely future:
Estimates for the realistic lifespan of mammalian species: Estimates for the realistic lifespan of mammalian species differ from 0.6 Million years (Barnovsky et al, 2011) to 1.7 million years (Foote and Rap 1996).
As a rough midpoint between these two estimates I apply Toby Ord and tell 1 million years.
Final dimension of humanity’s existence: As about 200,000 years of history are already in the lend a hand of us we would maintain end to 800,000 years left.
Measurement of humanity’s inhabitants: Fixed with the UN projections, the realm inhabitants will proceed to amplify for the relaxation of this century, however by the pause of the century inhabitants development will most likely be end to zero. The UN demographers set up a question to the realm inhabitants then to be 10.9 billion other folk. I’m assuming that inhabitants development continues a small bit further into the 22nd century and can fair then stabilize at 11 billion other folk.
As emphasized sooner or later of the text I’m pondering of this as an illustrative location that makes it that you might possibly presumably judge to worship the scale we’re absorbing in. It’s no longer a prediction and as with any scenarios about the a long way a long way-off future, the reality might possibly possibly prove to be very various; inhabitants development might possibly possibly proceed further or the realm inhabitants might possibly possibly decline.
Existence expectancy sooner or later: The UN demographers mission that many international locations can maintain existence expectations elevated than 90 years by the pause of the century. The sphere realistic existence expectancy is projected to be 82 years then. If we remove that the relaxation of the realm inhabitants can set up as a lot as the healthiest international locations in the duration after 2100, then a median existence expectancy of extra than 90 or 100 years is that you might possibly presumably judge (critically for the extra a long way-off future, extremely long existence expectations are that you might possibly presumably judge).
I remove a existence expectancy of 88 years in my projection. Here is elevated than the projected world realistic, however lower than the existence expectations projected for the acceptable-off international locations. It’s miles surely a rather conservative estimate if we opt into consideration that we’d attain a future in which health continues to crimson meat up.
So these are my assumptions for this location:
- 800,000 years final for our species
- 11,000,000,000 other folk dwelling at any one time
- 88 years of existence anticipated for the realistic person
Taking this collectively, how many younger other folk will ever be born after the three hundred and sixty five days 2022?
(800,000 years / 88 years per person) 11,000,000,000 other folk=
100,000,000,000,000 other folk=
100 trillion other folk will most likely be born in the next 800,000 years
When will the 1000th period be born?
In the 2nd chart I added this files as an annotation. One has to achieve rather a lot of assumptions to estimate this time limit. Here are my assumptions:
In a world in which the inhabitants is actual, every 2 other folk maintain on realistic 2 younger other folk who dwell long sufficient to maintain younger other folk themselves. This would mean that within every 88 three hundred and sixty five days duration there will most likely be as many births as there are other folk.
For simplicity we will give you the option to remove that one period is 22 years long (i.e., on realistic future other folk maintain younger other folk as soon as they’re 22 years venerable). Here’s an appropriate assumption because it formulation that every period is a quarter as long as the existence dimension of different folk on this location.
In this world every period would be a cohort of 11 billion / 4=2.75 billion other folk.
This suggests that the 1000th period from recently would be born in 22,000 years from recently. (This isn’t exactly honest because there will most likely be inhabitants development in the next century, i.e. it would opt a small bit longer than 22,000 years.)
In these 1000 generations there will most likely be 2.75 billion 1000=2,750 billion births.
Which formulation the need of births in the next 1000 generations would be 346-times greater than recently’s world inhabitants (2,750 billion / 7.95 billion=345.9).
How long will it opt till as many infants are born as there are other folk recently?
In the 2nd chart I added this files as an annotation.
Fixed with the UN projections there will most likely be 8,036,352,977 younger other folk born between 2022 and 2079. This suggests that there will most likely be as many younger other folk born in the next 57 years as there are other folk alive recently.
Humanity’s past, original and future in multiples of every various
The future in multiples of all other folk ever: 100,000,000,000,000 / 117,000,000,000=855-times
The future in multiples of the present: 100,000,000,000,000 / 7,953,952,577=12,572-times
The past in multiples of the present:
(117,041,198,802 – 7,953,952,577) / 7,953,952,577=13.7=rounded to 14
One trillion in multiples of the present: 1,000,000,000,000 / 7,953,952,577=125.724=rounded to 126 (Here is what I tell as the need of triangles per row.)
The need of future births over the next 5 billion years in multiples of recently’s inhabitants:
625 quadrillion other folk would be born on this location in the next 5 billion years: 625,000,000,000,000,000 other folk
Folks alive in 2022: 7,953,952,577 other folk
625,000,000,000,000,000 / 7,953,952,577=78,577,285
1.5 million years final: If Homo sapiens survives as long as Homo erectus
How long has Homo Erectus existed?
Homo erectus is an extinct species of venerable participants. It’s miles among the first recognizable contributors of the genus Homo. It became as soon as furthermore the first human ancestor to spread sooner or later of Eurasia,
Homo erectus survived for no no longer as a lot as 1.7 million years. The oldest fossils belief to be Homo Erectus are the Dmanisi specimens from original-day Georgia, dated to 1.8 million years in the past (Lordkipanidze et al, 2006). Basically the most most up-to-date fossils are from original-day Indonesia, and were dated to 0.1 million years in the past (Yokohama et al., 2008).
How expansive became as soon as humanity’s future if we survived as long as Homo erectus?
If we – Homo sapiens – live to boom the tale as long as Homo erectus we would maintain 1.5 million years left. Our future would be nearly twice as expansive as shown in the chart in essentially the major text.
Nearly 190 trillion younger other folk would be born into this world.
Here is the calculation:
- 1,500,000 years
- 11,000,000,000 other folk
- And the realistic person lives for 88 years
(1,500,000 years / 88 years per person) 11,000,000,000 other folk=
187,500,000,000,000 other folk=
187.5 trillion other folk would be born in the next 1.5 million years
[Alternatively you could see this by considering that 1,500,000 years is 1.875-times longer than 800,000 years.]
1 billion years: If Homo sapiens survives as long as the earth is liveable
How long will Earth remain liveable? How long will our solar exist?
Astrophysicist Jillian Scudder, Anders Sandberg, and Toby Ord counsel that our planet will remain liveable for roughly a thousand million years.
- Toby Ord’s ‘The Precipice’, critically footnote 40 in the first chapter.
- Jillian Scudder (2015) – The solar obtained’t die for 5 billion years, so why develop participants maintain most entertaining 1 billion years left on Earth?
- Anders Sandberg’s text for the BBC: Basically the most entertaining long-duration of time threats facing humanity. He furthermore explains what will happen when and why.
Fixed with the placement above this might possibly be a future in which 125 quadrillion younger other folk will most likely be born.
Here is the calculation:
- 1,000,000,000 years
- 1,000,000,000 years is 1250-times longer than 800,000 years
- 11,000,000,000 other folk
- And the realistic person lives for 88 years
(1,000,000,000 years / 88 years per person) 11,000,000,000 other folk=
(1,000,000,000 / 88) 11,000,000,000=125,000,000,000,000,000 other folk=125 quadrillion other folk would be born on this location in the next billion years.
A quadrillion is a one followed by 15 zeros (1,000,000,000,000,000).
125 quadrillion is 125 thousand trillion other folk (Fixed with the short scale).
5 billion years – as long as the solar exists
If humanity survived for thus long as the solar exists, 5 billion years.
- 5,000,000,000 years
- 5,000,000,000 years is 6,250-times longer than 800,000 years
- 11,000,000,000 other folk
- And the realistic person lives for 88 years
(5,000,000,000 years / 88 years per person) 11,000,000,000 other folk=
625,000,000,000,000,000 other folk=
625 quadrillion other folk would be born on this location in the next 5 billion years.
625 quadrillion is 625 thousand trillion other folk.

Over the next 5 billion years: 625 quadrillion=625,000,000,000,000,000
Over the next 800,000 years: 100 trillion=100,000,000,000,000
625,000,000,000,000,000 / 100,000,000,000,000=6,250
