So what happens when the alien also wakes up?
Living as an alien would just be another, possibly less unpleasant level of hell.
I believe there's no real "I", a soul, a playable character or whatever in the machine, my brain just pretends that there is one. I also don't see how an intelligent designer would put me in all this suffering for its entertainment. Existence simply allowed "me" to emerge, as it allows everything else in its infinity. But the true home is the eternally safe, absolute oblivion. One can never see it with the eyes or imagine it with the brain. I long for the embrace of nothingness.
But that's just my belief, I respect many different ones as well.
