So, a future where there is no market can only be a future where humans are extinct, in my opinion (some form of communism won't work)
If someone believes markets will still exist (one form or another) and there will still be exchanges of value between people, even in the most maximalist AI future - then I think it becomes rational for said person to seriously consider buying AI labs, even at stupid valuations
Admittedly I've formulated my previous comment wrong, I should've written "a future where AI has the potential to fulfill all jobs known today", instead of "a future where AI replaces all jobs"
As mentioned in other comments, I'm not trying to convince anyone to do anything, I'm here just to argue different points and positions
