Is the self all that can be known to exist?

[Aegon]

I find solipsism useless since there aren't any consequences to it. Even if I'm the only thing that's "real," everything else is so real to me that it wouldn't make a difference. But ignoring that, I don't actually find the idea frightening like many people do. What I find more frightening would be the idea that I'm just a very high-functioning simulation in somebody else's experience, and they're the only "real" one.
