On page 108 they seem to rule out the "gradual replacement" as
proposed by, I think, Ken.

Well, I haven't read the whole thing yet, but it also doesn't cater
for a world in which the brain to exist. That is, it assumes it lives
in our world, and not its own simulated world. So it would need to
have all the relevant interaction abilities that we do, to be a
typical replacement. Nevermind the possible attacks on it. Securing
brains from being manipulated would be important. Also, poor nature
would have no way to affect it via evolution. Which would mean we'd
kind of die.
