Why Are Tesla and Google Designing Their Own Processors?

Maybe another article - "This is your code on cpu's", this is your code on a FPGA, this is your code on an ASIC.... that kinda thing, but appreciate not many Hello World and looks folks at the fast fractals in play ASICS or dedicated CPU's, making such comparisons not that easy.

Yes the aspect that the Google affair with their TPU, more flexible, whilst not fully general purpose, I'd call them niche purpose. A decade ago we would of just called them co-processors. Time change, buzzwords change, but 8 bits will still be 8 bits.
