alright I'm gonna ask the naive question: how exactly does Brain make money? is it offered as an independent product? or is it's incremental contribution to the rest of Google that high? what even is Brain, to Google devs?
To me it's an umbrella for all of the projects that fell out of an initial realization (by Jeff Dean and his circle) that Google's infrastructure was large enough to put into practice a class of older ML ideas that had spent years being thought infeasible. They developed the means of training huge models, then useful models that resulted from that, and follow-on project like TPUs.
