I notice people do this a lot. The way I think about it is this:

If I believe that I can do better than someone with a career in X, that’s actually hugely insulting. Because with my assertion that I can do better, I’m basically saying that those people were all basically screwing around for the duration of their entire career. That my 0 years experience is comparable to their 5 or 10 or 15.

Luckily, we don’t have a bunch of super rich and powerful software people wading into areas where they have no experience and making a big mess because of assumptions like this. Right? Ha ha ha.
