From experience, you don’t need to not have a CS background to find TeX/LaTeX difficult or obscure to customize or extend.

Here’s a challenge to try (I hacked together something similar that only works in specific cases): write an environment where you get N columns in portrait page mode, with a vertical ruler, say, 12pt to the left of each column; respecting different paper sizes.

The amount of \makeatother, and what does that even mean??, will blow your mind

I’m not a TeX lover, but this part is just a snipe. I’m guessing you know and this was a joke. Apologies that it annoyed me enough to write this comment.

If you care enough to read this, you could learn the purpose of \makeatother [1]. It’s not tricky.

Apologies, my comment was poorly written.

I meant “\makeatother, and a lot of other things whose meaning is not clear”
