Blank stare.Laughter.What an opportunity!
You can make totally outrageous statements you will never be held accountable for!

Computing ⇒ cheaper, not faster (per proc)
Democratization of some HPC Traditional full-function PC will have
integrated high-end graphicsAt least TFLOPS (SP) on your lap
(for some value of “lap”) Cellphone/laptop; or
Yotta-cloud/fog/vapor Nothing in between, as far as you can tell Charged not by rack or proc, but by KWH
And possibly bandwidth.

ParallelismThere will be no savior language or architecture.
But data will be gigantic “embarrassing” or “trivial” parallelism Uninteresting, but practical
Parallel for power reduction: Pwr F2
more procs, constant time ⇒ lower power
