Comment on Hedonium's semantic problem

If you're in VR and can never leave it or see evidence of if (eg a perfect Descartes's demon), I see no reason to see this as different from being in reality. The symbols are still grounded in the baseline reality as far as you could ever tell. Any being you could encounter could check that your symbols are as grounded as you can make them.

Note that this is not the case for a "encyclopaedia Chinese Room". We could give it legs and make it walk around; and then when it fails and falls over every time while talking about how easy it is to walk, we'd realise its symbols are not grounded in our reality (which may be VR, but that's not relevant).
