I wonder what Robert Nozick would think of recreational drug use.<p>That is as close to that &quot;machine&quot; that we have in reality and its pretty clear people are willing to accept&#x2F;risk the negative impacts and use such drugs.<p>This being the case, I&#x27;m pretty sure, people would use that machine if it was legal and cheap. Similarly, I&#x27;m pretty sure at least some of those people would prefer it to real life.<p>Similarly, the only reason I prefer &quot;real life&quot; is the relationships I built with people. If I had been given the choice, say, 10+ years ago to have such a machine ... I&#x27;d prefer it to RL and the effort it took to build the kind of life I want.<p>So its a philosophical question with answer of &quot;it depends on the person and RL situation they have&quot;.
