Yes, I think the rollout of SoCs that you describe could very 
well occur.  I hadn't even considered those! I was thinking of 
the accelerators in phone SoCs.

Googling just now I saw an estimate of the number of "smart 
phones" world wide of over 6 billion.  That seems a little high 
to me but the number of accelerator equipped phone SoCs is 
certainly in the billions with the number trending to saturation 
in line with the world's population.

Anybody can hook into an accelerator library, and that will be 
fine for many apps, but with dcompute you'll have the ability to 
quickly go beyond the canned solutions when those are deficient.

Lots of ways to win with dcompute.
