Even today we're recognizing that compute does not need to happen here.
When we're talking about creating powerplants equal to roughly 5% of the insolation of Earth, I think we're sci-fi enough to discuss orbital datacenters or Mars datacenters or Jupiter fusion candle datacenters.
Orbital datacenters suffer from the same problem: limited surface area. You think cooling is a problem now? Try not having conduction or convection. Radiation is all you get. A huge proportion of the mass and size of the ISS is radiators, and that only has to deal with the heat of low-power electronics and a few measly human beings.
Using an entire Mars only nets us about a 2x multiplier for our energy expenditure budget. Then we need four planets to double it again. Exponential growth is a bitch.
Thermodynamics and the tyranny of exponential growth are going to win this battle every time, regardless of the unobtanium technology you try to invent.
Compute doesn't need to happen here, but it can, so it will. Building datacenters on Mars or Jupiter doesn't reduce our ability to build datacenters here, so naturally, they will still be built, everywhere that they can be. It's an orthogonal capability.
It's quite possible that with "infinite" energy we could do mass scale carbon capture to offset the increased temperatures by rolling back the greenhouse effect.
This is basic thermodynamics, not greenhouse gases. If you put some amount of energy into a system with a fixed surface area, you will get a minimum equilibrium temperature.
Greenhouse gases and Earth’s internal nuclear decay engine make the situation worse, but even without them this would boil the oceans.
The more I think about space elevator, the less I believe in it.
The material alone is in a quantity beyond what we can reasonably manufacture.
and the material needs to be perfect. All design we have today have cascade failure mode -- any material failure translates to a total catastrophic failure.
and geostationary does not really meant Geostationary. There are lots of jiggling everywhere. It wear down over time. and let's hope nothing resonance
and we need some maintenance / decommission plan. How can we decommission this when it fail or need upgrade?
We're not going stop doing something locally just because we can do it in space. There are definite physical advantages to producing next to consumption. We will most likely do both -- things that can be done in space will be done in space, and things that are better done locally will ramp up. There is no upper limit to energy demand, none whatsoever. Stopping production anywhere it could theoretically happen is a matter of will.
No, it doesn’t. It assumes we’re using it here. If we beam the power to Earth from space, it’s the same thing.

The greenhouse effect is not what's cooking the planet in this example, it's the heat that results from turning all that energy into work.
We use it in space too, we just send food and manufactured products down the elevator.
You aren't really trying in good faith to think this through are you? This idea is over half a century old. Not getting it by now is willful.

Why would we have stopped?
Humans seem deeply tied to Earth in ways the AI that's to be designing these powerplants is not.
