The VR Experience Machine
If a virtual world is fully interactive and indistinguishable from reality, and the relationships and achievements within it feel completely real, does the fact that it is virtual change their value?
Robert Nozick's Experience Machine plugged you into a passive simulation. The VR version is different: you act, build, relate, and choose. The world responds to you consistently. The people in it have stable personalities and genuine reactions to what you do. This variant forces a sharper question about whether virtuality is what actually troubles us about the original, or whether something else is doing the work.
What changes from Nozick's original
Nozick's Experience Machine offered a passive life: you float in a tank while a computer generates your experiences. You are not really doing anything; you are having experiences as if you were. Most people refuse, and their refusals tend to cluster around three objections: we want to actually do things, we want to be a certain kind of person, and we want contact with reality.
The VR version removes the passivity. You are doing things, in some meaningful sense. You make choices that have consequences within the world. You develop skills that accumulate. The people around you have memories of your shared history and respond to who you are becoming. This is not Nozick's tank.
The question is whether the remaining difference, the gap between virtual and physical substrate, does enough moral work on its own to change the answer.
Whether virtual achievements and relationships have real value
The strongest case for the affirmative is that what makes an achievement valuable is the effort, the skill, the overcoming of genuine difficulty, not the physical location where it occurs. A chess match played online is not less of a chess match because the pieces are digital. A friendship conducted largely through letters or video calls is not less of a friendship because the people were rarely in the same room.
On this view, a sufficiently rich and stable virtual world might support genuine achievements and genuine relationships. The substrate does not determine the value.
The strongest case against is that the virtual world was designed for you. Its challenges were calibrated by someone else's decisions. The people in it exist to populate a world you are living in. Even if they are sophisticated, they are not independent agents with their own lives that intersect with yours by chance. Relationships formed in a world constructed around your presence are structurally different from ones formed in a world that preceded you and will outlast you.
Whether that structural difference matters depends on what you think relationships and achievements are for.
Discussion questions
- Would you choose to live permanently in a perfect virtual world if you could not remember you had chosen it?
- Is the value of real experiences tied to their being real, or just to how they feel?
- What would be the first thing you would want in your virtual world?
