It's true that nobody has beaten nVidia yet, and that is a valid data point I don't deny.

But (as a reply to some other repliers as well), AMD was also chasing them on the entire graphics stack as well as compute. That is trying to cross the moat. Even reimplementing CUDA as a whole is trying to cross a moat, even a smaller one.

But just implementing a chip that does AI, as it stands today, full stop, seems like it would be a lot easier. There's a lot of people doing it and I can't imagine they're all going to fail. I would consider by far the more likely scenario to be that the AI research community finds something other than neural nets to run on and thus the latest hotness becomes something other than a neural net and the chips become much less relevant or irrelevant.

And with the valuation of nVidia basically being based not on their graphics, or CUDA, but specifically just on this one feeding frenzy of LLM-based AI, it seems to me there's a lot of people with the motivation to produce a chip that can do this.
