A forthcoming critique of David Chalmers (https://philpapers.org/archive/CHATVI.pdf) argues that VR isn't real because real reality or RR possesses (at least) five features that no VR simulation could ever reproduce:
1) RR involves genuinely causal regularities
2) RR is older than any machine
3) RR will outlast any machine
4) RR supports living bodies in ways that cannot be replaced
5) RR belongs to an entirely different category than artifacts
In your estimate, which of these five reasons is the strongest and most decisive?
