The Experience Machine Thought Experiment
In 1974 Robert Nozick published the book, Anarchy, State, and Utopia, in which he posed the following thought experiment: If you could be plugged into an “experience machine” (what we would likely call today a virtual reality or “Matrix”) that could perfectly replicate real-life experiences, but was 100% fake, would you do it? The question was whether you would do this irreversibly for the rest of your life. What if, in this virtual reality, you could live an amazing life – perfect health and fitness, wealth and resources, and unlimited opportunity for adventure and fun?
Nozick hypothesized that people generally would not elect to do this (as summarized in a recent BBC article). He gave three reasons – we want to actual do certain things, and not just have the experience of doing them, we want to be a certain kind of person and that can only happen in reality, and we want meaning and purpose in our lives, which is only possible in reality.
A lot has happened in the last 50 years and it is interesting to revisit Nozick’s thought experiment. I would say I basically disagree with Nozick, but there is a lot of nuance that needs to be explored. For me there are two critical variables, only one of which I believe was explicitly addressed by Nozick. In his thought experience once you go into the experience machine you have no memory of doing so, therefore you would believe the virtual reality to be real. I would not want to do this. So in that sense I agree with him – but he did not give this as a major reason people would reject the choice. I would be much more likely to go into a virtual reality if I retained knowledge of the real world and that I was in a virtual world.
