Urs used to talk (internally) about not publishing "industry-enabling papers" which is why most Google infrastructure papers were describing something that had already been turned off, or was already in the process of being replaced by the next system (GFS, Vitess, etc). The things that did get published were either considered not key advantages, that other companies simply cannot do, things that other companies wouldn't bother doing, or experiments that never worked at all. There were exceptions of course. But it led to a public perception of the Google stack involving mostly technologies that were long dead or were never adopted.

"Attention Is All You Need" was a very very different thing and I also wonder if they are glad they published it. But I imagine if they hadn't, the motivation for researchers to leave Google would have been even larger.

FWIW I’d buy SNAP now that they are at rock bottom

Google makes a competing product to Claude's main product? So competing, in fact, that they have to ban Googlers from using Claude in order to get enough dogfooders.
