Are you for real?

Today we simulate city traffic in computers to optimize roads, traffic lights and speed limits. Pilots fly simulated flights with wind, gravity, other planes, land, sea and much more.
Do you think we, to study evolution, ever will try to simulate life in an artificial environment? If you do; Congratulations! You are already living in one!
Nick Boström (Director, Oxford Future of Humanity Institute, Faculty of Philosophy, Oxford University) argues that one of the following alernatives must be tru:

1) The human species is very likely to go extinct before reaching a “posthuman” stage.
(2) Any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof).
(3) We are almost certainly living in a computer simulation.

Here's Nick's paper.
