Having fpgas on-board feels like something that would have been a game-changer even pre-ai. Imagine if your Ryzen chip could do hardware encode/decode of h266 the moment the spec was finalized.
At the hyperscaler level there's been a lot of adoption of SmartNICs, which are often FPGA based. That makes me feel like there's a pretty big market here already for integrated FPGAs. I think the other requirement is that these FPGAs need to be made broadly available if we're going to see a real shift. Selling a couple many-thousand-dollar high end chips isn't going to create new audiences clamboring for these things, which is required for the tech to actually get interesting & well adopted, instead of existing only in a small but important niche.
