   Very correct.

   In some respects it's a "how do we DEFINE computing ?"
   sort of thing. A bunch of Nvidia chips doing "AI" is
   one way of looking at it. The peta+ FLOPS you may want
   to solve a supernova implosion or horrific math equation
   is another. In short 'performance' now has to take a cue
   from "What We WANT done" rather than the olde-tyme
   benchmarks.

   Not everything can be 'parallelized' either ... some
   jobs just require vast instructions-per ...

   As said elsewhere, 'pure photonic' tech MAY provide
   the ultimate - 10x to 100x what we're seeing with
   the low-nanometer transistor designs. But, in this
   universe, that's kinda IT.

   We need a new universe.
