As a guy with an MA in fine Arts who now leads a technical job I think this is an arbitrary decision.

I would draw the line differently. The line needs to be between people who have to care about how things work and people who are not willing to or don't have to care.

If you are in a tech company ideally everybody cares to some degree about the product. And caring about the product means understanding the different alternate-reality versions of that product and comparing them. And that requires some technical knowledge.

If you're the janitor or the security at that company that does not apply to you. If you are running a team, guess what.
