Is the following a correct restatement of your point?
Somewhat. I'm not saying that lessons should be standardized in the same way that textbooks and exams are currently standardized. I don't think enough resources are being applied towards textbooks and exams (considering how widely used they are, even a small improvement would have a big effect because it'd be multiplied by the amount of people it touches).
My central point is, "I sense that there is a more abstract economic principle behind what I'm trying to say. Can anyone help me to articulate/understand it?".
That would not be very efficient, because 100 employees...
You're right. The 100 employees example was bad.
On the other hand, a teacher needs to adapt the lesson to the class.
I agree. I don't think that lessons can be so good that we don't need teachers (yet). I think that there will still be holes in the students' knowledge after/while going through the lesson, and the most efficient way (right now) to identify and address these holes is to use a human.
It looks like your point could be summarized, in economics jargon, as: education is now a field where the superstar effect should apply.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
