Yes, I agree. On page 68 he points out that the types of problems pre-EM are very different from those post-EM, but it could be that availability bias makes the former seem larger than the latter. We are more familiar with them, and have broken them down into many sub-problems.

Paradoxically, even though this 'taskification' is progress towards EMs, it makes them appear further away as they highlight the conjunctive nature of the task. Our estimates for the difficulty of a task probably over-state the difficulty of easy tasks and under-state the difficulty of easy tasks, which could mean that breaking down a problem increases our estimate of its difficulty, because it is now 10 tasks-worth-of-effort rather than one-tasks-worth-of-effort.
