Nvidia didn't innovate into AI. Developers used their gaming cards for AI. They kinda got into that situation by pure luck. I wouldn't trust they will be able to pivot into the next big bubble if it's quite outside their area of expertise.
> They kinda got into that situation by pure luck.
This statement is wildly inaccurate. NVIDIA made deliberate and strategic moves to dominate AI and it made them a very long time ago. They didnt fall into this yesterday by mistake.
Even ethash had ASICs. As long as there is enough financial incentive, there can always be ASICs built for cheating the system. "Any cryptocurrency worth its salt" would have that incentive.
