Amazon ran for, what? 20 year with no profit.
So what's the precise, documented, real, non-projeced/hypothesized issue?
Regardless, Nvidia does have financial interest here.
Profit is a weird metric, in that one can defer necessary expenditure to show increases in it, while having negative profit was a good signal for Amazon as they invested all that money.
The labs are not really in the same position though, as their major capital expenditure is training models, which keeps getting more expensive and they can't stop as the frontier keeps moving.
We'll see when the S-1's come out I guess.
