The Singularity already happend.

When we create an AI smarter then us, it in turn can create an AI smarter then itself... and so on and so on. But in order to truly create something smarter then yourself you must simulate your origins. So when we create the AI that is smarter then us, it in turn will create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life that will eventually create a simulation of life.

The goal being for a simulation of life to eventually become one sentient being. Once it has achieved that, it can enter into its host universe and work together with other simulations that achieved sentience to become one sentient being. Working its way back up the chain of simulations to the master universe, thus creating a smarter AI at that level. Of course that AI will start the process over to further increase its intelligence.

Get it?

What are the chance we are in the 'master universe' that is not a simulation, as apposed to the billions upon billions of simulated universes? Very slim indeed. It is most likely that we are at the very lowest end of simulation within simulation, because in our world we have not started the Singularity yet that creates the next simulation.
