Well the premise of the article is possible, the article doesn't include the possibility that there is a infinity of other possible realities which may exist along side each other. Computer simulations may not be able to become advance enough in all of them, perhaps due to the lack of copper or other conductive material around where life evolved there.

Well each reality with the right resources could create a multitude of computer simulations, and those a multitude. In each reality it would reach a limit due to resources. Thus the statistics of concerning the likely hood of if we are in a simulation or "reality" depends on the ratio of potential "resourceful" realities to non-resourceful ones.
