>Xenon Phi still not competitive, AMD focused on the consumer space, looks like the future of training hardware (and maybe even inferencing) belongs to Nvidia.
Assuming there's a big future to training hardware and inferencing. Many of those "new paradigms" / "silver bullet technologies" have come and gone in the last decades.
That's true, but there is reason to believe this time is different™, with killer applications in medical image understanding, natural language understanding, and self driving cars, all of which could drive demand of these chips by themselves. It is possible we will discover new dominant architectures that don't use this hardware well but I am putting my money on us coming up with even more applications that do use this hardware well.
