Q&A:

1. Talk about keep the humans in the driver seat : particular kind of intelligence that generates war, torture, etc. Possible to engineer an intelligence without baggage? Even if it is not superintelligent, maybe turn world over to it.  We can't give up our faults because of what we are.

    - We carry around "bloody baggage". Going forward, intelligence will be nicer in positive sum game.  Playing positive sum games because much more plausible (with higher intelligence).

    - Phenotypic evolutionary changes may have stopped with civilization, but culturally we've improved in last 5 centuries.  Reason to be optimistic.

2. Do you believe climate change will have a significant impact on the singularity?

    - Possible existential threat if it leads to nuclear war.  Not one of the most serious existential threats that we would face, however, so "probably no".
