yes hard to say but we I think I head it speculated that we could have had warp drive 500 years ago and settled many nearby stars by now if events transpired differently from the days of ancient Greece onward through the Dark Ages and beyond. We would be a whole lot more advanced, that's for sure, if we had put all our energy into peaceful cooperation and helping each other, pooled all our resources and intellectual talent into constructive technology instead of destructive technology, and so on. We can still get our shit together, but we better start now as we could all be dead tommorrow if some huge disaster happens.
