What atrophies with calculator usage is an ability to do long form division for example, or arithmetic operations with large numbers in your head for example.

The way you describe AI - tell it the problem and get an easy answer sounds identical to anecdotal complaints I've heard like Google search providing an answer to everything means no one has to learn anything, or everyone copying code from stack overflow articles. At the end of the day it's still another tool with pros and cons, tradeoffs, etc., and will be used and misused and abused by different people in different ways.
