For the general public Id agree with you, for professors (of any subject) I would set the bar way higher.

Have you seen the university entrance exams from 100 years ago? When going to university actually meant something? I would say less than 1% of people currently at university at this time would pass them.

The student body got dumber as university changed from being a beacon of enlightenment to a profit maximiser, and the standard of professor dropped equally as sharply.

It took me 15 minutes to teach my chief commercial officer git and now she uses it every day. Expecting a university professor to understand a version control system is not hard, its only hard if the professor is an idiot and we (collectivly) accept that as ok
