Doesn't technology erase gatekeeping behavior while removing learning barriers?

[u/Automatic_Office_925]

I was wondering if the past era of gatekeeping and hoarding information is over in educational institutions? I am referring to rural environments or small cities with a less diverse range of books or school choices...

Mechanics of gatekeeping before 2010:

* Incompetent teacher: say bye, bye math, the probability of learning it drops considerably.

* No cash for private sessions, well too bad, you are just left behind your peers that can pay for that extra information.

* The teacher doesn't like this class so he hoards info or is just plain cryptic confusing everyone.

* An authoritarian teacher, might as well not ask anything or it's going to be a humiliation ritual.

* Oh, you're a textbook cowboy now. Gee, but there are no answers at the end for most of the math problems.

It seems technology should really remove barriers making anything much easier to learn for the upcoming generations: languages, blue collar skills, science. The present tools free at your disposal are insane, I would not have dreamt possible as a kid starting school in the 90s.

I'm not clear what kind of information hoarding you mean?
