My prediction is that eventually we'll see the "small embedded" market
squeezed down by rather cheap powerful devices such as the rPI. My argument
for this prediction hinges on power becoming free in the future (due to the
current massive advances in solar and wind energy on top of better
batteries).

Currently, the power draw of the stronger chips is too high and production
at scale means that shaving off a few cents here and there is worth it.

But it looks like the price tag of a 1.2 GHZ 64 bit chip is only going one
way, and this makes the added development effort of targeting a smaller
chip more expensive. In turn, you need an even bigger scale of production.
And so on.

GRiSP is interesting because it can offer you a far faster time to market
and lower development effort at the same or better robustness/resilience.
You can thus get the lower production costs while amortizing development
effort better. It is a good bet until the niche squeeze I predict above
happens.
