> I'm pretty the situation is not confined to Columbia. This is how crazy the film/movie world is.

It's not limited to the film/movie world either... this is the unfortunate truth of most MFA programs: they don't launch careers, unless you're looking to become a MFA teacher yourself.

In other words, Multi-Level Marketing

Indeed this is certainly more broadly applicable. But if this is the case for a school as prestigious as Columbia in New York City (i.e., a city with a thriving television industry), things must be even more dire at no-name liberal arts colleges in flyover states.

"Those who can't do, teach" is fitting for many fields of study

Actually, those who "can't do", generally "can't teach" either. One surefire way to get better at doing something is trying to teach it, in fact.

I get what the quote is trying to imply, (and why) but it's totally backwards.

It always annoys me when I see that quoted. The original idea applied to people like athletes - you do it when you can, but when you're too old to compete, you can still teach. Nothing to do with ability, and in fact, it assumes more ability on the part of the teacher.

From my experience, athletes who were really good at the sport wasn't the greatest teacher; since they kind of intuitively understood how they should conduct their body to do something, they had a real tough time trying to transfer that knowledge to me who has no idea how I should move my body. They often tried to use imaginary that didn't really connect with me. It was far better to be taught by someone who was good but wasn't a natural as a beginner since they seemed to have a better grasp on what kind of struggles normal people had.

Obviously this is just anecdotal and probably changes at the Olympics levels and other places where the learner competency and affinity is already high.

I've tried tutoring people in academic subjects I know really well. I find myself unable to explain what they're doing wrong because I cannot put myself in their shoes. Try teaching algebra or calculus to someone who doesn't get it, and let me know if your skills really help with that.

Depends on what you're teaching. In engineering circles it's been said that those who can, do; those who can't, become Six Sigma consultants.

Or agile instructors / scrum masters.

That'd be the SW equivalent, yes.

Not really. One can have the knowledge and understand the mechanics of a trait, and is still unable to succedd in this trait. Especially creative fields are guilty of this. Similar is sports. A great coach can still be lousy player. Because at the end for success you need far more than just knowledge.
