I agree - a dystopian hellscape is more likely if humans are no longer needed for any labor. Entertainment and hobbies will only take you so far. Even now pursuing constant entertainment or pleasure gets old quickly if you have no purpose, no goals. Humans thrive on being challenged, thrive on working to support their family, and thrive on competition among themselves. Without purpose (no matter how small or big it is) there is no humanity. Unless we regress back to primitive times and become simple like other animals whereby our only purpose to survive is to reproduce.
