I think the amount of turmoil around these deals is giving more weight to the possibility that we’re in a massive bubble thats quite divorced from any kind of fundamentals. Sooner or later the bubbles gonna burst.
Anthropic ARR went $1B -> $4B in the first half of this year. They're getting my $200 a month and it's easily the best money I spend. There's definitely something there.
Economic bubbles _usually_ aren't based on things which are entirely worthless; there's generally _something_ there (just not enough something to sustain the valuations). There are exceptions (NFTs, arguably cryptocurrency as a whole, and of course tulips), but those _are_ the exceptions.
