> replace AI with calculators

Seriously? Idk about you but we weren't allowed to use calculators until long after we had already learned how to do whatever the calculator did by hand, except in cases where that was never the point of the lesson to begin with (like calculating cosines). And even then, sparingly. The reason they eventually let people use it was that it had nothing to do with the lesson being taught, and it was a waste of time at that point to make us do arithmetic by hand. Not because it suddenly became OK to turn off your brain and become lazy.
