ok the thing about people who feel trapped in scenario 2 is, don't you realize you are already trapped?
human beings are unimaginably constrained already. to another alien species, the human condition probably sounds as horrifying to them as scenario 2 sounds to us.
morever, don't you realize that we are already trapped in our brains? that piece of cake sitting in front of you. you don't even know if it exists! that cake only exists inside your mind, and so does everything else in the world.
sure, you might to mad a few times in this eternity, but can it really be that in all of infinite time, you cannot devise a method to amuse yourself? do you truly believe yourself to be so incapable of adapting to the world around you?
