Most don't care to understand technology, they are only interested in consuming it. If all were lost tomorrow, how long would it take for us (humanity) to return to this (our current) level of technology? 2000 years?...more?
Well you see, that all depends. I'm betting that a big guy with a purple mohawk, driving around in a dune buggy converted for post-apocalyptic, highway combat will make some geeky engineer type his bitch.
That will last until Mel Gibson (who would have been a police officer at the time), comes along and rescues him, along with a whole village of militant cave children and Tina Turner. From there, we will be able to rebuild a seriously hot retro 80's world WITH all the gadgets.
So no, not 2000 years. Idiot.
