I don't know who did that, but they did a pretty brilliant job. The low-level software stack and the hardware stack, okay, you've got your nice regular high-performance hardware, you've got these great torus-shaped interconnects, and then you've got the right low-level collectives, the all-reduces, et cetera, which I guess came from supercomputing, but it turned out to be kind of just the right thing to build distributed deep learning on top of. Oh here's another interesting implication: Right now, we think about the growth in AI use as a sort of horizontal- so, suppose you're like, how many AI engineers will Google have working for it? You think about how many instances of Gemini 3 will be working at one time. If you have this, whatever you want to call it, this blob, and it can sort of organically decide how much of itself to activate, then it's more of, if you want 10 engineers worth of output, it just activates a different pattern or a larger pattern.
