Ie, "listen to me, the distinguished lecturer."

Non-educators, those not explicitly trained in how to educate, don't understand there is more to teaching than lecturing.

In a non-adult setting, good luck trying to get away with any lecturing at all.

Plenty of adults can't even converse without looking at their phone, so I doubt lecture-style works for them either.

If a "grizzled engineer" wants to make an impact in education, the best way is to teach a building block skill thoroughly and effectively, and on a platform that's free and easy to access. Leave the public school teachers to do they're jobs, they're actually way more competent than they get credit or compensated for.
