A whole universe, an M-brain, and there's nothing better to do? Come on! Felines sleep 12-16 hours a day because they are bozos. Imagine, with all that mental power at your command, and physical power over the universe. Wouldn't you spend time thin

OK, while we are constructing the SI's as predators, look at it this way. Imagine that they are all in fierce competition - there can only be one! - which there may be reasons for. Even if a small number of them think this way, the rest must at least adopt a strong self defense stance (I would if I had an SI gunning for me!!!).
Say you stop thinking, and rely on automated (or smaller, slightly less intelligent) subsystems to keep an eye out. Meanwhile, another killer SI (KSI?) is thinking, thinking, thinking... it models your alarm subsystems, works out a way to attack you without alerting you (they are quite clever by definition), and good bye sleepy head! In general I think proactivity is more successful than a reactive stance in a competitive situation.
Why would it do this? Maybe it can examine the corpse, steal the energy reserved for when you next woke up, and continue on it's high-energy strategy, off to nuke the next SI. Meanwhile it's also been able to devote substantial resources to some long term goal, like the fundamental meaning of the universe, or some similar guff.

Is it possible that SIs will discover that a lower level of processing (dumber self) which is sustainable over longer periods of time, such that the SI is constantly "awake", is more advantageous than short periods of mega-brain activity punctuated by long periods of sleep? Maybe some combination is possible; maybe that is what you might also mean by periods of inactivity - you would instead have periods of comparitive stupidity.

I still don't like it. I can sleep 12-16 hours a day now if I am so inclined (not really, but that's out of choice too). Why would I transcend to (S^N)I-hood, just to go for a trans-galactic snooze?
Emlyn (the milky way really *is* a huge line of speed for SIs).
