The circus cast has everything they need at the moment right? Caine is by their side, they can acess any world ever created by him, design their own adventures, have sex and many others. They can have and do anything that their human selves would never have.

But the thing is, when you have or can do anything you want, life grows boring. Whenever you want something in real life, you have to struggle for it, be it working more, studying more, whatever, to achieve whatever it is that you want. Many people say that this struggle is what makes life worth living, because the reward at the ending feels deserving, you conquered it, no one snapped their fingers and gave it to you. After all, if you have everything you want anytime you want, what is the point of living?

I am sure that not having to worry about feeling sick, eating and drinking whatever you want, doing literally anything you want will be fun for many many years, but the cast's creativity will run out eventually right? They may have accepted that they are not actually humans at the end of episode 9, but their minds are still human nonetheless, with the very human desire of..y'know, achieving something?

But maybe I am crazy. What do you all think?

I know it sounds morbid but.. won't all of them end up abstracting anyway?
