If I’m going to be happy anywhere,
Or achieve greatness anywhere,
Or learn true secrets anywhere,
Or save the world anywhere,
Or feel strongly anywhere,
Or help people anywhere,
I may as well do it in reality.(originally from the book Rationality: From AI to Zombies)
— Eliezer Yudkowsky , Elizier talks about how we assume that if we were in an alternate universe, e.g., with magic, we'd study magic and become heroes . But in that universe, magic would be real. So, it would probably lose its excitement and be just as mundane as what reality offers. So if you imagine yourself a hero in that alternate universe, why not be it in this one?
