You don't have a solid sphere, you have collectors in multiple orbits differing not only in height, but also in angle WRT the plane of rotation of the star. You build it piece by piece, and it's working from the time the first piece is put into orbit. But I really prefer topopolis, which is also built piece by piece, and is easier to get around in. (In the Dyson sphere variation all the pieces need to be separate...which is a real problem. Of course, one could do a cross between the two, and have multiple topopolis instances in slightly different orbits and at slightly different angles.)

In both cases the trick is to use a design where you can start with just one piece, and expand from there.

Billions for Drones is a good investment - as long as we are getting millions of them. If that is the cost of 1 drone, then no.

But it should also involve a decrease elsewhere. Cut the ridiculously stupid battleship and replace it with a Drone carrier.

They aren't bullshit concepts, but they also aren't even nearly practical now. Give it time. The Dyson sphere (practical variation) would need at least several centuries to be practical, and even then I think topopolis is a better approach, but it's not a bullshit concept. The "space AI" probably needs sustained space-based industry to become practical, and that, itself, has a few problems to overcome, but it's reasonable eventually.

But they are not using those renewables to displace coal internally. They still prefer to use coal as fast as they can mine it or import it.

I don't think that's accurate -- the only people who "prefer to use coal" are in the Trump administration. China, like the rest of the rational world, prefers to use whatever energy source is cheapest and most effective, which might be coal in some situations, or it might be solar, or nuclear, or hydro, or something else.

The chatGPT makers are NOT among the smartest people, you have fallen victim to propaganda.

The technology behind ChatGPT was invented by:
  Dznuret Bahdanau, Kyunghyun Cho and Yoshua Bengi in
https://arxiv.org/abs/1409.0473/ in May of 2016.

Everyone else just copied their work with minor improvements and adding immense amount of memory and processing.

Most of the guys who currently are in charge of the Large Language Models are more interested in money than in science. They are above average intelligence but are in no way the smartest people on the planet.

there is a difference between a scientist that invents and/or discovers science, the engineers that figure out how to implement the science, and both are different than the money men that keep the gravy train rolling.

The guy at the top makes business decisions and never ever invents stuff. The scientists are lucky if they get paid anything for inventing it. The engineers always get paid - but not as much as the money guy on top.
