Excess AI capacity? Huh? Wait a minute does that mean they've built more data centers than there's demand for? Oh! How did that happen? Well, I'm a complete idiot, a layman, not even a developer, what do I know about economics and technology...
In retrospect, this seems pretty easy for Meta to have done as heretofore they were a single captive customer AI shop.
Like they have much lower cost of capital than OpenAI or Anthropic for example and far more direct to consumer muscle, if they could've gotten their models into a better position it's very possible they could've beaten out OpenAI on consumer AI. Probably a smaller prize to win than B2B AI but still huge.
And then if the case where AI is panning out but they are failing to execute (where we appear to be now) they have the option of becoming a SpaceX style NeoCloud that is pretty solid, even though most of their moves were pretty bad along the way.
