Video 1 - Very relevant look toward the future
Video 2 - Hated it . . . garbage to me.
Video 3 - Superintelligence - While caution is good, AI will be logical, not emotional. It is more likely that AI will find humans to be useful, and, if transhumanism takes off as I suspect it will, as long as it is kept in the public domain, it will likely have more inherent benefit to humans and spur on exploration of the universe in ways we find difficult to imagine today. I am far MORE worried about what HUMANS are going to do with their shitty combination of fragile egos and nuclear weapons than I am about AI.
