One thing I don't understand about their architecture is that they have spent so much effort building this monster of a chip, but if you are going to do something crazy, why not work on processing in memory instead? At least for transformers you will primarily be bottlenecked on matrix multiplication and almost nothing else, so you only need to add a simple matrix vector unit behind your address decoder and then almost every AI accelerator will become obsolete over night. I wouldn't suggest this to a random startup though.
