All share price fundamentals based on the long term have this pesky thing called discount rate which means your [hypothetical] earnings from something expected to happen in 2050 get weighted a lot lower than your 2028 earnings and your 2100 earnings barely figure in it at all though.

That's the case on a pure "I could invest my money in something that makes a bigger profit now, and use that money to buy shares in the longer term bet afterwards" basis, but is even more the case when you factor in uncertainty. And "SpaceX's 2026 near monopoly of launch and the 2026 datacentre build rush will still be relevant once we're far enough into the future for inference chips to not need regular replacement and orbital megastructures to be cost competitive with ground ones due to the amount of orbital recycling going on" is pretty uncertain...

Well, at least that is what they teach you in college when you learn about the efficient market hypothesis. In reality, investors are getting less rational every year. The modern stock market has become pretty much decoupled from reality.
