But the big question is if this prevents memory growth. Suppose I use a
fraction of my energy to produce positronium or something similar to
store my information in as I grow. Would the energy needed to communicate
with my remote memory banks become prohibitive? As I understand it, a
sufficiently slowly growing being would never have any problems with
redshifts *inside* itself.
And a sufficiently large being can contain other beings. While the
universe cools and slows down, we are partying inside a splendid
posthuman virtual universe with an unbounded future.
