Advent of No-AI

I sense that it can make things hard to learn, and abolished it from my practice on Leetcode. It's not permitted for contests, and the magic or subtly wrong answers don't facilitate learning as well, and obscure the leaps you can make by iterating (more slowly) on your own inferior solutions. Pain is an OK teacher.

I've been doing Leetcode in Rust which, statistically, is a poor choice. When I have asked, it writes solutions that look like python or C, unable to identify when iterators are the appropriate tool.

It's not authoritative reference material, which my background in IT trained me to strongly, strongly prefer to, even my own intuition in situations I've seen before.

“Raw-dogging it” as the kids like to say.
