You'll only lose the skill of critical thought if you don't spend the time it frees up solving other problems.

This is the lazy part of the argument: The assumption that people stop applying themselves when they get a tool to replace one part of a task.

A "deep" tool that fully automates fairly specific tasks works this way. LLMs are more of a "shallow", general tool that can partially help with lots of different things, but none so completely that they alleviate the need for human involvement in them.

You're making the opposite argument of what you think you are.

Say more.

If you look around and fail to see this already happening, you are part of the problem.
