Tech companies sitting on godlike amounts of money and being able to invest such huge sums in AI at a nascent stage is worrisome. There is absolutely nothing to indicate that this is anything close to an optimal distribution of investment in the economy. It's not a plus that some of these companies are playing an investment shell game. They don't hand out awards for badly timed investments, they hand out bankruptcy rulings. It's fine and good if a few speculative companies go bust. Nobody will think it's fine when companies ingrained into the fabric of the economy do. At the end of the day it's clear we've learned very little from previous crashes and I think it's a false assumption to think we'll suffer equivalently for it.
