I love this thread!
All of this slightly tangentially reminds me of Eric Weihenmayer who I think was the first blind person to climb Everest and he had this theory about sighted people who have this "even I" syndrome.
Here's an Q&A he did about it:
INTERVIEWER: Explain what you mean by the "Even I" syndrome.
WEIHENMAYER: It's funny, because people will come up to me after a presentation, and they'll say, "Man, I think that's so incredible what you did. Even I with two perfectly working eyes couldn't make it up Everest." And I laugh, because here's a guy who lives in Orlando and smokes a pack of cigarettes a day. It's like, "Dude, do you think the difference between success and failure has to do with perfectly working eyes?" It's a compliment in their minds, so I take as that, and laugh. Two good eyes may be part of the equation, but there are so many other qualities that make a person successful, like the skill and talent you develop, the time you devote to it, and your persistence
INTERVIEWER: And the fact that he has a beer belly and hasn't exercised in two years.
WEIHENMAYER: Yeah, you're 70 years old, you're in Orlando, you've never walked more than a mile in your life. What makes you think you could climb a mountain with perfectly working eyes? It goes well beyond that. They mean it as a compliment, and I accept their intent.
