I buy that. In our moon simulation example, let's make it really good. Exact. Even you have to complete a simulated astronaut training program and fly there and it's all sufficiently plausible in it's realness. But even if you do this a hundred times, I think if you could actually go to the moon, and even if it's not any different from VR in any major way -- I think it's likely it would feel different. That you know nothing mediates your senses from reality, you would most likely pay a special type of attention to all it's details as real details. And you'd look up at the Earth and damn. That's it! What happens if you could fool your brain into believing that? Where does it become unethical in manipulation? Where does it all become nonsense? These are the things I struggle with.A place can have value because you can't just teleport yourself there.
