Ask HN: Why are expert practitioners often so bad at teaching beginners?

There's a very large gap of which the mid-tier is as natural to the expert as typing. I see this a lot in math, where the best lecturers are usually fairly junior.

My best friend has trouble reading graphs, as in y-axis, x-axis kind of thing. He doesn't know whether < means bigger or smaller. This is something a lot of experts have internalized decades ago, so we'd completely overlook how hard it looks to a beginner trying to learn comparison or AND/OR in a condition.

With respect, I think it is reasonable to assume post primary school education. The example given is perhaps a poor one.

He has a college degree, albeit non-STEM. This stuff is taught in middle/high school here if you're not in STEM.

Also I've taught coding bootcamps and after a few batches, I set up expectations that, no, you can not learn programming from "nothing" like the ads say. You're expected to know touch typing, basic math up to algebra, and how to open files on your own device. Those who don't know these things should get a refund and try again for the next batch.
