One factual and one meta opinion
Let's start with the factual opinion: The important part in today's AI workloads is not so much a question of performance alone (you can throw a lot of hardware against it), but of performance per unit of energy consumption. It is rather hard to believe, that even the smartest trick can make a general purpose CPU work as efficient on such a specialized problem than a specialized (i.e. GPU) accerlerator card.
Now the meta opinion: Whatever is bad for Facebook is good for me. YMMV.
