There's an imperfect truth to the comment you're replying to.

You're right that it's unnecessary to emulate the brain down to its finest implementation details, down to the molecule or even down to the cell.

However, I contend that it's essentially impossible to create a "relatable AI" (an AI that behaves and thinks like humans do) without proper consideration of embodiment. A large part of why the brain works the way it does, at a macro level, emerges from the vehicle it's in, and broadly speaking both its afferents/inputs and efferents/outputs.
