Cows are essentially slaves to human beings. The meaning of their lives is to either give milk or be eaten. It is true that some cows live in horrible conditions; however, kobe beef cows live a pretty good life. Kobe beef cows get large pastures to roam instead of being constantly confined to a stall, they get to enjoy a top notch diet for cows, daily massages, and they even get several beers a day on the house. Even though they end up as food, kobe beef cows lives a pretty good life.
So, say something similar happened to humans. Say either an advanced alien race or hyper intelligent AI took over the world and gave you the choice to be a slave for them and live an awesome life, or reject slavery and fight back.
In short, if aliens or AI offered you your idealized life in exchange for your enslavement, then which would you choose?
