Why should the Internet be accessible only to people who have undergone a high school curriculum that teaches it? That already excludes a large portion of the population.

Why exactly should the interrnet accessible for all people at all? When you are too lazy or dumb to use a browser like it was in 2000, you will too think that facebook or insta are the internet. Thats the problem on today's internet. It's too accessible for too many ignorant people.

I don't see the point of your argument. I don't see any reason for excluding people who "think that facebook or insta are the internet" from it. If you desperately require more powerful tools to support the way you use the internet then there are powerful tools available; why use the lowest-common-denominator tool that is the browser?

I couldn't resist adapting your argument for food:

Why exactly should food be accessible for all people at all? When you are too lazy or dumb to grow your own food like it was before the coming of Jesus, you will think that McD's is the agriculture industry. That's the problem with today's agriculture. It's too accessible for too many ignorant people.

To a first approximation, school can't teach anything. Most of your high school class don't remember what DNS is.

DNS? Is that a high school level subject?

I was going to say something about how you needed to know what DNS is to know how URLs work and how all this is easily teachable at the high school level, but I realized I'm just out of touch. Amend my comment to say that the previous poster's classmates can't tell apart a search bar and a URL bar either.

I also question if you need to know what DNS is to know how URLs work. "This name is how your computer finds the website you are looking for" is sufficient for some level of knowing what a URL is and how it works.

And URLs, canonically, don't require DNS to function.

To a first approximation, you are talking out of your arse.
