So far, fine.

Does Remez imply there is a little man in our heads, thinking for us?

Again, do they mean we have extra minds in our heads? Then what's going
on in those minds?

What you should have said is that there is no homunculus problem with
computation. The homunculus is unnecessary; computation is mindless and
mechanical rule-based symbol manipulation.

What do you mean? How do we use dolls in our heads? And who uses them?

This reply is rather vague and in some places seems confused; kid-sib
certainly couldn't get an understanding of the homunculuc problem from
this unless he alreday knew it in advance.
See the skywriting and skyreading on this topic to sort it out.
