Yes! We are not trying to claim that P vs NP is underrated in the video, just the bit with interpreting it as a question about inverting functions. I think using "underrated" is justified, I talked with a bunch of people about this topic and it was a new way of looking at it for a lot of them.

Of course, using the title "What P vs NP is actually about" is a bit of a stretch -- "Interesting take on P vs NP" would be more honest.
