Is your brain truly unimportant enough that you don't care about the shape it is in?

[ See, here is where the misunderstanding lies. Because while Alice can readily accept the idea that someone may be able to just remove their brain like that - wouldn't be too weird by Wonderland standards! - she doesn't think that said brain could be a different one, meant for different purposes. At least, not initially. ]

Even if you can somehow survive without, I'm assuming you'd still be using it for some thinking.
