Glad you found it interesting!
It tended to come from people focused on that area but the concerns were not exclusive to technologies (or even xrisk more broadly).
To put it another way, people were concerned that “EAs tended to help their friends and others in their adjacent peer-group disproportionality to the impact it would cause.”
Regarding polarization in “Intercommunity coordination and connection,” my sense is this came from different perceptions about how past projects had gone. No clear trend as to why for “community member improvement”
I think the way this is reconciled is the view that “current organizations are highly capable and do prioritization research themselves when determining where they should work.” But prioritization including that type is hard to do right and others would struggle to do an equally good job.
P.s. reminder these are not my or CE’s views just describing what some interviewees thought.
