On the ethics point as a "best bet", consider also the importance of a sense of humor that recognizes irony. As I wrote in 2010: https://pdfernhout.net/recognizing-irony-is-a-key-to-transce... "There is a fundamental mismatch between 21st century reality and 20th century security thinking. Those "security" agencies are using those tools of abundance, cooperation, and sharing mainly from a mindset of scarcity, competition, and secrecy. Given the power of 21st century technology as an amplifier (including as weapons of mass destruction), a scarcity-based approach to using such technology ultimately is just making us all insecure. Such powerful technologies of abundance, designed, organized, and used from a mindset of scarcity could well ironically doom us all whether through military robots, nukes, plagues, propaganda, or whatever else... Or alternatively, as Bucky Fuller and others have suggested, we could use such technologies to build a world that is abundant and secure for all. ... The big problem is that all these new war machines [and competitive companies] and the surrounding infrastructure are created with the tools of abundance. The irony is that these tools of abundance are being wielded by people still obsessed with fighting over scarcity. So, the scarcity-based political mindset driving the military [and economic] uses the technologies of abundance to create artificial scarcity. That is a tremendously deep irony that remains so far unappreciated by the mainstream."
Yes, absolutely prescient! Quite the irony.
Just as our abilities to solve problems accelerated without bounds, it will be our paranoia that screws things up.
Even before machines have any incentive or desire to turn on us, the fearful & greedy will turn them on all of us and each other.
I hope things don’t go that way. But it’s the default, and I think the greatest risk.
