Weird fallacy that if you use a tool you can't use your brain anymore

Like people who use machines are always physically strong enough to do the job the machine does, right?

This is not what a fallacy is.

I think it's pretty obvious that people who offload their thinking to an LLM will eventually get used to not thinking hard about things. Anything you do that you stop doing regularly eventually atrophies. Thinking hard about things and performing on work is as much a skill as it is an innate property of being smart, as evidenced by the many "prodigy" sort of folk who languish in obscurity later in life.

If you a tool that replaces your brain then you won't use your brain.

A lot of people do outsource their thinking to AI, so it's not that weird to bring up. That's effectively how many AI companies are marketing the technology.

But it's definitely possible to use AI without letting it think for you. OP should at least acknowledge that.

Those who dogmatically refuse AI outright may be disadvantaged for some things in the future. But it's also probably hyperbolic to say they will be "left behind".
