But people have been saying this about CUDA for twenty years, and we are not any closer to a replacement GPGPU paradigm today.

The root comment in this thread was about Nvidia hedging their bet on lost AI market share. They recognize that a reduced pace in training and inference competition will undercut their business, but CUDA isn't a one-trick pony for LLMs alone. TPUs are - you can't even reuse the same architecture for training and inference, they're separate ASICs unlike CUDA cores/ALUs. Veterans of crypto mining will tell you that the ASICs lost in the end, as Nvidia was evolving their hardware faster than the ASIC manufacturers could iterate. When the crypto acceleration landscape diversified away from ETH/BTC into altcoins, Nvidia was still there making money hand-over-fist from mining hardware.

I guess you could argue that robotics, world models or computer vision won't be a trillion-dollar market. But Nvidia is positioned to be the first mover in all of these markets, and none of their competitors are even coming close to the integrated stack that they sell consumers.
