IA is likely to go up in big steps, but IA FOOM makes even less sense than for AI because of the human in the loop. Also, it would probably give humans a lot of improvements before solving the problem of low number of independent simultaneous attention threads. So it is not clear that any IA direction would produce a situation of single unstoppable entity.

If IA simply greatly increases the thinking power of a thousand people by different amount, I would not be sure that medium-term existential threat of this field is greater than overall short-term existential threat created by something existing here and now like Sony...
