The comments so far seem focused on taking a cheap shot, but as somebody working on using AI to help people with hard, long-term tasks, it's a valuable piece of writing.

- It's short and to the point

- It's actionable in the short term (make sure the tasks per session aren't too difficult) and useful for researchers in the long term

- It gives us a specific vector to look at, clearly defined ("coherence", or, more fun, "hot mess")
