I'm surprised the perspective of China making TPUs at scale in a couple of years is not bigger news. It could be a deadly blow for Google, NVIDIA, and the rest. Combine it with China's nuclear base and labor pool. And the cherry on top, America will train 600k Chinese students as Trump agreed to.

The TPUv4 and TPUv6 docs were stolen by a Chinese national in 2022/2023: https://www.cyberhaven.com/blog/lessons-learned-from-the-goo... https://www.justice.gov/opa/pr/superseding-indictment-charge...

And that's just 1 guy that got caught. Who knows how many other cases were there.

A Chinese startup is already making clusters of TPUs and has revenue https://www.scmp.com/tech/tech-war/article/3334244/ai-start-...

Manufacturing is the hard part. China certainly has the knowledge to build a TPU architecture without needing to steal the plans. What they don't have is the ability to actually build the chips. This is even in spite of also stealing lithography plans.

There is a dark art to semiconductor manufacturing that pretty much only TSMC really has the wizards for. Maybe intel and samsung a bit too.

For China there is no plan B for semiconductor manufacturing. Invading Taiwan would be a dice roll and the consequences would be severe. They will create their own SOTA semiconductor industry. Same goes for their military.

The question is when? Does that come in time to deflate the US tech stock bubble? Or will the bubble start to level out and reality catch up, or will the market crash for another reason beforehand?

China has their own fabs. They are behind TSMC in terms of technology, but that doesn't mean they don't have fabs. They're currently ~7nm AFAIK. That's behind TSMC, but also not useless. They are obviously trying hard to catch up. I don't think we should just imagine that they never will. China has a lot of smart engineers and they know how strategically important chip manufacturing is.

This is like this funny idea people had in the early 2000s that China would continue to manufacture most US technology but they could never design their own competitive tech. Why would anyone think that?

Wrt invading Taiwan, I don't think there is any way China can get TSMC intact. If they do invade Taiwan (please God no), it would be a horrible bloodbath. Deaths in the hundreds of thousands and probably relentless bombing. Taiwan would likely destroy its own fabs to avoid them being taken. It would be sad and horrible.

There are so many trade and manufacturing links between China and Taiwan that an outright war would be economically disastrous for both countries.
