#63Google has always had great tech - their problem is the product or the perseverance, conviction, and taste needed to make things people want.

#64Earlier quoted context omitted.
Not very. Those fabs are vulnerable things, shame if something happens to them. If China attacks, it would be for various other reasons and processors are only one of many considerations, no matter how improbable it might sound to an HN-er.
What if China becomes self-sufficient enough to no longer rely on Taiwanese Fabs, and hence having no issues with those Fabs getting destroyed. That would put China as the leader once and for all.
Totally possible, but the second order effects are much more complex than "leader once for all". The path for victory for China is not war despite the west, but a war when the west would not care.

100 times more chips for equivalent memory, sure.

#66This is the “Microsoft will dominate the Internet” stage. The truth is the LLM boom has opened the first major crack in Google as the front page of the web (the biggest since Facebook), in the same way the web in the long run made Windows so irrelevant Microsoft seemingly don’t care about it at all.

#68A question I don't see addressed in all these articles: what prevents Nvidia from doing the same thing and iterating on their more general-purpose GPU towards a more focused TPU-like chip as well, if that turns out to be what the market really wants.
Everyone using Nvidia hardware has a lot of overlap in requirements, but they also all have enough architectural differences that they won't be able to match Google.
OpenAI announced they will be designing their own chips, exactly for this reason, but that also becomes another extremely capital intensive investment for them.
This also doesn't get into that Google also already has S-tier dataceters and datacenter construction/management capabilities.

#69> It is also important to note that, until recently, the GenAI industry’s focus has largely been on training workloads. In training workloads, CUDA is very important, but when it comes to inference, even reasoning inference, CUDA is not that important, so the chances of expanding the TPU footprint in inference are much higher than those in training (although TPUs do really well in training as well – Gemini 3 the prim…
