Maybe build something useful that solves a real problem?

That’s the problem. For now at least, we’re at the end of “new tech make line go up”. Crypto wasn’t it, neither were NFTs, LLMs are no different. All the low hanging fruit was picked a while back so they’re stuck trying to make us believe that there’s a Next Big Thing just around the corner when, at best, there’s some fairly niche and difficult to monetize tech requiring vast resources to work.

Corrected, thanks!

We even have small nuclear reactors that can use spent fuel from the larger ones, thus solving in part the disposal of it.

Do we? Last I heard there aren’t any in service.

Furthermore, significant advances have been achieved on fision power.

We’ll need a hell of a lot more advances before fusion is even close to powering a grid.

The C suite and management of these companies want two things - for the stock to go as high as possible, and for them to be able to sell at the top and leave a bunch of bag holders wondering what the fuck just happened.
