Apropos schadenfreude, I don't have a dog in the fight---I don't even actively use LLMs, because they don't work for how I'm wired.
I'd like to have a future-dog in the fight though. I want the LLM-hyperscaler bear case to happen because I want access to dirt-cheap compute, which I hope will be the aftermath of a financial failure of the hyperscaler junta. What will be left is industrial capacity to make tons of chips and computers, which I hope translates in to dirt-cheap retail compute. eCoin-world is unlikely to absorb all that because mining unit economics and coin volatility are both significant enough to make people consider the bet.
And like, LLM tech is quite cool and useful and all (ignoring for the moment, the planet-scale piracy by the hyperscalers), but the other "normal" stuff is so much more so.
As for the odds of them making a God, I'm taking an inverse Pascal's wager, as I wrote here: https://news.ycombinator.com/item?id=50427160
I would like a world of cheap compute too really, but I fear at this point it could only happen if all AI demand suddenly disappeared and never came back. Given how fast it is growing and how far it still has to grow, compounded by the limited rate at which new capacity is being built, it seems unlikely we'll get to an overbuilt state for an extremely long time... unless, like you said, there are dramatic breakthroughs in computation efficiency.
I skimmed through the "After the AI Crash" paper, and it is really not an analysis but a policy brief that mostly reiterates, and uncritically accepts, a lot of the large numbers thrown about in other media sources. There is no analysis of the demand side and cash flows and timelines involved, and spends a lot of time on the circular investment issue with any attempt to unravel it.
The exponential view analysis is much more methodical and finer-grained in its approach, and it addresses a lot of the aspects you mentioned, including prices and demand.
As for whatever Michael Burry has said, I've looked into it a bit (as an outsider, no inside knowledge) and I don't quite buy his thesis. There are indications from too many different sources that GPUs are economically valuable for much, much longer than the timeline he assumes.
A good thing to Google AI Overview would be "How many market crashes has Michael Burry predicted?", and wonder why all those other predictions didn't get the airtime this one is. I have a theory: https://news.ycombinator.com/item?id=50421245 ;-)
