I think you might be overestimating the worldwide impact of that, though. AMDs are used for "mining crypto" - they're the best for that purpose - and no, that also is nothing to write home about. Despite being very present in my personal circles.
The amount of people doing either is minuscule in comparison to gaming. Those buying big for datacentres are definitely accounted for by nVidia. They don't buy GTX cards.
Everyone I know who are doing deep learning have been buying Titan X's or GTX 1080's - their "gaming" cards. Not the datacentre or pro viz cards.
