Maybe but it's not like all those AI compute units or whatever Nvidia called them will be thrown in the dumpster after the AI bubble pops. There's a lot of problems the can be solved on them and researcher are always looking for new problems to solve as compute becomes accesibile.
I'm tired of hearing about Nvidia's "luck". There was no luck involved. Nvidia shiped Cuda on consumer GPUs since 2006. That's almost 20 years time researchers had to find used cases for that compute and Nvidia made it possible. In other words the AI bubble happened because Nvidia made the necessary ground work for it to happen, they didn't just fall into it by luck.
They will not be thrown in the dumpster, but that's actually a bad thing for NVIDIA. We had a very short period when lots of miners dumped their RTX cards on ebay and the prices fell a lot for some time. (then AI on RTX became a thing at small scales) When the A100/H100s get replaced, they will flood the market. There's many millions of $ stuck in those assets right now and in a few years they will dominate research and top end of hobbies. Only high profile companies/universities/researchers will look at buying anything newer. Maybe NVIDIA can do 2 generations of those cards, but ASIC-based solutions will hit the market and the generic CUDA will become a problem rather than a blessing. Same story as BTC miners and graphics cards.
Sure, they didn't get lucky with the tech they had to offer - that was well developed for years. They just got lucky that the next big thing was compute-based. If the next thing is memory/storage-based, they're screwed and the compute market is saturated for years - they have only gamers left.
