Just for fun: Not only are we living in someone's holodeck fantasy, it's a badly written holodeck fantasy!

Let me weigh in on what I consider to be the worst possible catastrophe of them all. One that would explain every stupidity in the world today. That we are living in a very poor simulation.

...

All right, the notion is gaining some degree of plausibility. But suppose it's true. In that case, whose simulation are we living in? Some vast future Omega Point consciousness? Aliens, simulating weird alternative life forms? (Plausible, since human beings are so crazy.)

Naw, it should be simpler than that. And much more consistent with the irrationality we see around us?

How about this one? That we are all living inside someone else's Start Trek Holodeck dream. Is there any way we could test this hypothesis? A method that goes even deeper than cybernetics, neurophysiology or even physics?

Simply look around and see who has been impossibly fortunate, vastly out of all proportion to personal talent and competence, or even family privilege, or even any possible intervention by anomalous good luck!

Next, consider that a long-lasting Holodeck experience will not just be about being lucky, winning every poker hand and getting every girl. Heck, that's boring. Sitting around in a harem on a pile of jewels? feh. Gets tired quickly, take my word for it!

Anyway, if you simply win every hand, it's hard to forget that this is a simulation. If that is your aim -- to live in a wish fantasy while still being able to pretend it's real -- well then you want all the cool stuff to happen in ways that at least marginally let you fool yourself... into believing that you earned it all. Not because you dropped a lot of quarters into the Holodeck slot, but because you're more deserving. Because you’re gooder. Because you're better than everybody else.

Yeah! That’s the ticket. Tell the Holodeck computer to simulate real opponents - all the smug, assured, brainy types you hate. Only in this new universe they will lose despite all their fancy book smarts.

And your allies? Fun guys who know how to party and help you give wedgies to the smug, smartypants nerds. Yeah! As for luck? Well, set the game to easy, of course, but with LOTS of nerds to overcome and lots of social rules to flaut. And while victory should follow victory, it should never be TOO obvious. Make it gradual enough to last. So you can avoid the real enemy. Boredom.

All right, then, folks. Can YOU see anybody around you whose life we must clearly all be revolving around, in his personal holodeck program?
