This is a hypothetical question, then. In that case the sky's the
limit (so, somewhere around 100 km).

Replace with what? More brain? A little pointless if there isn't any
injury involved, but we'll probably be able to grow substitute
cortices in the lab somewhere along the line.

Higher-efficiency components would be more interesting. At that point,
though, the question becomes: what would work better than what we
have, yet still be compatible enough for parallel implantation?
