my (personal, intuitive) take is that sam harris was right (back in his 2016 ted talk) about ASI/God.
those who are optimistic about ASI are not taking human nature into consideration. $$$, power, control (hence war, ownership, etc.).
humanity is Creating Superhumanity, and to think that superhumanity will be shared equally is to completely ignore the nature of living beings, like men.
the optimistic take (much longer) is here (see kurzweil; singularity): https://www.youtube.com/watch?v=ykY69lSpDdo
simply skipping-around the ray kurzweil singularity video shows a level of optimism that does not take into consideration:
- power & control motives
- individual motives
- military motives
- $$$$$$ motives
- a cancer's motives*
- etc.
-the end.
