If I had some degree of control over what I could see, then it might be interesting. As it is, I spend a significant proportion of my life surfing the web, reading interesting articles, watching YouTube etc. If I could do something like that, even if I had no impact on it, that might be something I'd sign up to. Especially if I had the option to 'sleep' for a while, or to turn myself off altogether.
But if it was an entirely passive experience then no, that sounds like hell to me.
