This 100%. I have been playing guitar since around 1972, and am really good at it. I will never offer lessons to anyone, at any level, because that is a completely different skill than just being able to play a guitar.

I also know instructors at bootcamps that are not master programmers, in fact more than a few don't meet senior-level expectations; but they are exceptional at explaining the basics, triggering those "lightbulb" moments in their students, that makes them a far better instructor than someone with vastly more experience and expertise.
