Agree with absolutely everything you wrote, but to nitpick: this happens at 10 trillion people on a planet like Earth (Isaac Arthur did the math in his ecumenopolis video). We could go higher with some sort of radiators to transmit waste heat into space, but probably not to quadrillions. The broader Solar System, however, could certainly support quadrillions, and that's before Type II stuff comes into the picture.
Ah, my mistake, it's been a while since I've seen that video. But yeah we don't need to stop making little imps and monkeys anytime soon. Btw are you planning on redoing your timeline in future fiction anytime soon? Used to love reading those with my old account.
Hard to predict a thousand years ahead but it certainly wont be anything like option 1 unless we experience some kind of nuclear holocaust where the survivors are just sterile twits.
Humans are very attached to where they set down roots. So I don't see humanity abandoning earth. Option 2 wouldnt happen unless the fate of humanities existance depended on it, and even then there would be some who would stay until the bitter end.
Humans might be idiots, but we arent stupid enough to just go and dye off like that. Or am I placing too much faith in humanity??? Probably too much faith. Alright I'll grant you that one as a valid option
And we don't need to reduce the population at all. Purely because we literally have everything we need on earth to support not trillions, but quadrillions of us. The only time that we won't be able to sustain that many is if we breed to the point that the very heat our bodies and machines will incinerate us. And even then we'd probably just install climate controll systems. What people sometimes dont realise is that we can build down as well as up, and keep doing so for a very very long time with the aid of technology. So option 4 is a bust as well.
Populations will grow and our habitats will verticalize with it. There is no need for population reduction.
Here's the thing.
If I become a rich man, rich enough to have my way, I won't allow quadrillions of people to infest Earth. I'll force many to move off world if I must. And I'm sure many others feel this way. In fact, I know many people feel this way.
That's what you're not understanding. Just because we can doesn't mean we should, and even if we could that doesn't mean we will.
Good luck moving Americans XP . And it wont be a huge problem for an ecumenopolis. If need be we can just build further up and down. I've come to become a firm believer in that we can build infrastructure to get ourselves out of any resource problem or such and such. But yeah, I can definitely see rich asses wanting the planet for themselves when it belongs to all of mankind. Alright add being forced out as one of the potential reasons option 2 could be a thing. Human stupidity and greed. Mind the uproar and kickback but.
so if we take the , leave the earth option, can we visit it for the sake of tourism? what would happens to the animals and indigenous people that live there? would they end up changing in some ways? like, if we had the means to finally teraform the moon and stay there for many years then come back to explore the earth, would the humans that were left behind call them, moon people?
like, this would make for an aweosme sci fi story. thanks thread.
Nature reserves or gene banks for animals, probably gene banks considering what it would take for us to abandon earth.
Of course the indigenous peoples will have to change. Look how much everyone and everything has changed from year 0 - 12017 HEC (nearly 12018 now .... wow time flies) Groups might get their own reserves to practice out their way of life. Or someone might have the bright idea of saving space and placing them all in FIVR to live out their lives however they please without taking up as much valuable land space. The idea is a little morally bankrupt but we're talking the future here, and the future is anything but not inherently fucked regardless of the systems put in place or how it all works societally and technologically.
If we went to the moon to live or something I can guaruntee you we wouldn't be able to terraform it without a LOT of work. We're talking multigenerational and that is WITH a Sol scale trade network carting gas all over the place. Theres the issue of a magnetosphere and getting all the right gasses in place. Rotating the moon so you'd have an ok day and night cycle, keeping the atmosphere in place, and I havent even gone into what low gravity does to bone density and bodily organs over time. No you'd have people living in old lava tubes or highly protected and pretty fucking huge geodesic domes if our tech gets to the point where it can survive and be maintained in such conditions (probably is already but theres just something about huge lasers or missiles shooting asteroids out of the way that screams "if it fails we're screwed"). And will even enough people get there under those circumstances if at all to provide a stable gene pool where you dont have too many people engaging in incest to keep the population growing? and how will babies and little children be made to exercise so they dont lose all their bones?
I'd recommend some kind of habitat in space where you can maintain earthlike gravity with centrific force (or is it centrifugal? I always get those two mixed up) at least then people can live similarly to how they do on earth now without too much worry.
