Uberti: Future AI token factories will cost $40B to $100B per mega-cluster
“You could have the same kind of thing for some futuristic mega cluster.
Forty billion dollars, hundred billion dollars as a giant mega token factory serving one or a handful of models for a massive number of users to get that same economies of scale thing.”
Uberti: AI models will eventually do all kernel generation superhumanly
“And when the models keep getting smarter, they'll eventually do all of it. They will become superhuman.”
Uberti: Individual trillion-dollar data centers are inevitable
“Absolutely. It is a matter of time. It's like asking, what do you say, a billion dollar fab, or a ten billion dollar fab, or a hundred billion dollar fab? It is inevitable that the economies of scale don't stop at, oh, forty billion dollars is the magic number…”
Uberti: High-speed AI decode is bottlenecked by data movement, not math
“When you do this sort of kernel's work, what you realize is that the math is relatively easy. But to get high speed decode, the thing that matters is data movement. Almost all the work that you do is optimizing how do you move data around a single chip or acro…”
Uberti: TSMC funded an experiment on Etched's recommendation and updated its line
“TSMC customer service is way, way better than I have seen at any other company in any other industry. It's the kind of thing where if you say, hey, you can approve your yield by making this change, you can go make them a recommendation, and then we'll go run a…”
