They should feel stupid, for obvious reasons. I assume there's a "not" missing from that statement but, just like the next example,

I'm here to learn. If fully understanding XYZ was a prerequisite for getting anything out of the talk, then either the presenter failed to communicate that ahead of time (their fault) or, I chose to ignore, or completely missed, the prereq (my fault, I'm objectively stupid, presenter is not to blame).
