The people with experience also aren't necessarily the ones that end up teaching - which isn't to say the same information can't be conveyed necessarily (e.g. good academics keep up to date with the field in industry) but there is powerful focus that practical experimentation brings.

The ones with experience are most often not the ones teaching. You know what they say, those who can’t do… teach.

Some people like to teach

I know. I love to teach too. But I’d never take it up as a profession. The vast majority of successful people who have a yearning to pass on their knowledge hand select a few protégés or write a book.

I have had one teacher who was like that. He’d been involved in the development of nuclear weapons before he retired. Incredibly smart guy. Unfortunately, he couldn’t teach physics worth a dime. He had the highest drop out rate of any physics teacher at my college.

Those two scenarios cover the vast majority of cases.
