I think the comparison to a calculator isn't fair because a calculator serves a very discrete purpose. Your brain can compartmentalize a calculators function.

I have been using ChatGPT to code & write copy for a week and its abilities are so broad that my brain couldn't really slot it into a specific area. The result is my brain started reaching towards it every time it felt strained. I had a similar thing happen when I was googling a lot of info for work and then found myself considering searching for things like "when is my dads birthday?". My mind couldn't slot its function into a specific area like it can with a calculator.
