I get it. I see no room to be perplexed since he explained it.

Aside from that, in general, requiring a student to do without a magic tool so they are forced to percieve and understand some fundamental that the magic tool hides, is hardly a new or perplexing concept. Otherwise, you get exactly what he just said, they got.

He's not talking about education, but about professionals producing prototypes.

And designing a part to be manufactured easily with the intended process is a basic mechanical engineering skill.

He certainly is talking about education, at least, exactly as much as I was by using the word "student".

"student" just means "one who studies". It doesn't say anything about what they study or what kind of building or organizational structure they happen to inhabit at the time.

The principle I attempted to articulate is general and applies in any context, including this one.
