Remember the old saw "You only use 10% of your brain."? Yeah, that's wrong, but what is almost completely true is "You only use 1% of your transistors."
We have a zillion free transistors and they spend all their time idle--even on tiny, battery powered electronics. We haven't even scratched the surface of what to do with all these transistors.
I have two entire Linux machines that communicate in such a way merely to open a door. And I only feel slightly guilty about being that wasteful. :)
Everybody programs embedded hardware with dongles with underpowered microcontrollers. Why? Put an entire Linux computer behind it (RPi or Beaglebone)--now what can you do?
The current failure of tech is lack of imagination. Or, perhaps more charitably, lack of competent implementors (hardware and software) with imagination.
Transistors are free--now let's build something out of them.
