This relates to why online education hasn't replaced traditional schools. As I wrote for InsideHigherEd:
"But having a real-human teacher watch them causes most students to pay more attention, and this comes without any cost in rigor. Just by sitting next to my son I can increase his level of attention and I suspect the same is true with most learning. So even if online education drastically improves, and is able to present in a fascinating manner everything currently taught in college courses, having an instructor -- plus online material -- would allow courses to teach students even more than most of these students could learn from the online courses alone."
having a real-human teacher
Do you actually need a real-human meatbag teacher? Or would a sufficiently sophisticated virtual avatar be good enough?
What if you could impress your VR waifu by doing math problems? X-D
LW has a problem. Openly or covertly, many posts here promote the idea that a rational person ought to be able to self-improve on their own. Some of it comes from Eliezer's refusal to attend college (and Luke dropping out of his bachelors, etc). Some of it comes from our concept of rationality, that all agents can be approximated as perfect utility maximizers with a bunch of nonessential bugs. Some of it is due to our psychological makeup and introversion. Some of it comes from trying to tackle hard problems that aren't well understood anywhere else. And some of it is just the plain old meme of heroism and forging your own way.
