Even if it’s written by Eliezer, that’s still generalizing from fictional evidence. We don’t know what the laws of physics are supposed to be there..
Well. You probably can’t use time-travel to get infinite computing power. But that’s not to say you can’t get strictly finite power out of it; in Harry’s case, his experiment would probably have worked just fine if he’d been the sort of person who’d refuse to write “DO NOT MESS WITH TIME”.
Playing chicken with the universe, huh? As long as scaring Harry is easier than solving his homework problem, I’d expect the universe to do the former :-) Then again, you could make a robot use the Time-Turner...
