Would you plug into a machine that guarantees a lifetime of perfect simulated happiness?

Philosopher Robert Nozick asked whether people would choose to enter a machine that produces any experience they want, indistinguishable from reality, for the rest of their lives. Most people say no, which Nozick used to argue that we value more than just pleasurable experiences, such as actually doing things and being a certain kind of person.
