Re: Could we manage without technology?
The good thing about the "what if" is that it's impossible, I guess. Electricity is a natural phenomenon that's just movement of electrons, so it'll always be around as long as protons and electrons are around.
But we'll do just fine without electricity, but not without some serious problems with restructuring the world. We'll probably rely on gas and coal as fuels even more than now, and apartments probably wouldn't live for too long after electricity goes away. Medicine moves back to a more family-oriented style as well for a while. The good thing here is that knowledge doesn't go away with electricity, so in that sense we'll be ok for a while.
The thing is, we'll most likely pour billions into researching some sort of alternative energy, which eventually gets us back to where we are now anyway.
