I seriously doubt it.
I guess putting in a bluetooth enabled wireless network system into every lightbulb in the house might be interesting. Having one for every window and door in the house too might be promising. Also having every power socket networked to monitor power consumption would be nifty.
My first thought is I would seriously doubt it would happen. But then I remember many years ago having lunch in the company lunchroom, and I was explaining how my homemade computer at home had a Z80 keyboard processor, a Z80 terminal processor, and a 6800 main CPU, plus a 6502 cpu in the dot matrix printer too. One of the senior engineers at the time stated that that was such a rediculous waste of computing power, you only need one to do all of that.
I think hackers, pirates and criminals will drive it. We'll need all that processing power primarily for security in order to prevent someone from getting access to all that computing power in our home, car and such. A simple 8 bit processor can handle much of this, but then security is the big issue, the encryption algorithims and codes need a lot of processing power to make them secure.

I doubted it too, then I read the article which is put together really well - Jim Turley really did his homework, and now I believe.
