All these tools only replace mechanical aspects, not thinking ones. AI is truly unique and unprecedented in that way.

A spellchecker is purely mechanical, it just helps you spell your essay right. But it won't make your essay good, or help you write the right essay.

Integration in calculus often required me to "guess" a strategy ahead of time. It was more similar to searching for moves in chess than solving long division. Some moves would make it easier vs. harder and some would seemingly be a dead end.

WolframAlpha usually got to the correct answer, but often used a non-human strategy for integration. Generally, the best way to do it was simpler than what WolframAlpha's "step-by-step" showed, which was rather "brute force" and inelegant.

So, again, I agree. But again, it's a matter of degree and encompassing more domains vs. a binary change.

It's a different degree sure, but it's a big enough leap I consider it a different thing. It's similar to paying someone to do your homework or write your essays. Your critical thinking approaches zero, which is really bad for education.
