> We have the least amount of war ever in the history.

Sure, but now all it'd take is one nasty one and the uninhabited surface of the planet will be glowing for several million years. Having the sword of Damocles hanging over mankind's head 24/7 isn't nothing.

>better technology has always turned out positive for us humans in the big picture, even given short term drawbacks.

So far, sure, but the more powerful technology becomes, the greater the chance that the initial drawbacks are more than we can survive. Civilization survived the invention of nuclear weapons (...so far) through little more than blind, stupid luck. There's no reason to think that it's inevitable we will always survive great leaps in technological capability.

At this point I think we have no real choice but to push forward and try to progress while avoiding the dangers, but technological advancement is an existential threat and that threat should be respected.
