This isn't a Marcus stan account, though it superficially resembles one.
"Each new bigger, more expensive model ekes out measurable improvements, but returns appear to be diminishing and none of these experiments has solved core issues around hallucinations, generalization, planning and reasoning."

A trillion dollars is a terrible thing to waste
The machine learning community is finally waking up to the madness, but the detour of the last few years has been costly.

America is too corrupt to be governed.
The fight over AI regulation isn't about the technology -- it's about whether Washington or the states get to set the rules, and what happens to consumers caught in between.

A failed raise will be proof the bubble is popping. My guess is it’ll start with OpenAI or Anthropic, which need billions to just fund day-to-day operations, failing to raise even a fraction of what they were seeking.
That or a high-profile partner pulls out entirely.

Yeah, horseshit. Oracle's never getting that $300b bag from OpenAI. Coreweave's debt service is 6x operating earnings. Softbank could only cobble together $7b from 21 different lenders in the spring, versus $21b it promised.
They'll all be paying double-digit coupons from private credit.
