One of the arguments against space tourism as a long-term market is that as the VW technology advances, the real thing may actually be viewed as boring compared to the possibilities offered by programmable realities. I suspect that this will be true to some limited degree (particularly given the cost differential of doing things in cyberspace as opposed to meat space), but I’m sure that there will always be “Luddites” who refuse to hide in virtual worlds, protected from real consequences, but will prefer to go out and test their bodies and senses against the real thing.
