"Offloading the cognitive work" - maybe some people become less with AI - think of akin to a calculator.

I'm brilliant.

I do math better with a calculator. So does everyone, my brilliance doesn't change that I am human, a calculator will not forget to carry a one to oversimplify, it is smarter to accurate use a calculator to do math problems... is there something wrong with that?

Why is this different?

It's probably good for young people to learn to do arithmetic by hand. I think you'd lose some important cognitive ability if you never learned arithmetic other than to punch things into a calculator. Not so much because of arithmetic itself, but because you learn how to do careful step-by-step operations, surely an important general cognitive ability.

Once you can do it by hand, by all means use a calculator for speed and accuracy.
