The topic as I understand it is how the "default future" espoused by SIAI and EY focuses too much on things that look something like HAL or Prime Intellect (and their risks and benefits), and not enough on entities that display super-human capacities in only some arenas (and their risks and benefits).

In particular, an entity that is powerful in some ways and weak in other ways could reduce existential risks without becoming an existential risk.
