Hard to have vendor lock-in without vendors! Not that I think anyone should be lining up to produce what appear to be clones of the Intel Xeon Phi.

Funny thing: modern Xeons are getting closer and closer to the core and thread counts of the Xeon Phis. A 6980P has 128 cores and 256 threads, with AVX-512 and AMX.

It always made more sense as the host CPU; the Knights Landing product was vastly more useful. The problem has always been hanging your compute on the far end of a PCI bus. In AI when you're just shipping FP16 around it doesn't matter as much, but in the HPC world we want FP64, and I/O constraints kill this product dead.
