As I read this it occured to me that this is actually a lot like functions and fields/variables in programming. A function could be compared to a question where the result/answer it returns can change every time it's called/asked based on the current state of the system. A field holds an answer that is only valid for a time. The field gets "old" when it's not actively updated, but the function keeps being "fresh" because it's evaluated every time. It also compares nicely to answers being fast as a cache and functions being slow because the answer to the question has to be evaluated every time. Maybe a cache invalidation system for our brain would help us unstuck from held beliefs. I don't know. Just a few thoughts.
Fun comic!
The contradiction in the middle prevents the view espoused from being consistent. And of course, like most ideas of this nature, the writer violates all the rules in the explanation itself!
Lastly, there was no indication the writer knew he was writing satire so we get to laugh at him and not with him, I'm sure that will satisfy many readers!
