I remember when the whole AI craze was just getting started we were all pretty much in agreement that, of course, we would not give the things unfettered access to the Internet. That would be reckless and silly. Oh dear...
by "we" you mean an extremely small group of people who read lesswrong. Everyone else was immediately wanting to do it
I also remember a group of people actually seriously discussing Roko's Basilisk (the idea that some superintelligence will torture anyhone who didn't try to help develop advanced AI), to the point of me getting banned because I refused to stop making fun of it, because me doing so could anger some future super-intelligence.
