No big secrets really, just simple economic reality: AI doesn't make any money.
OpenAI is a giant money fire, burning hundreds of millions of dollars, to run a wildly unprofitable service that can't do any of the things it claims to do.
It turns out running giant GPU farms with the energy footprint of some small nations to spit out bad autocomplete is absurd, and the economic reality is catching up to them fast. User numbers are declining, the big launch of the new "faster" GPT-4 Turbo tanked their servers so hard they had to suspend new subscriptions, and in any case they lose money on every single user and search.
We're in an economic crunch, and now it's coming for AI, just like anyone with brains knew it would.
