Since nobody can actually prove it for 100% I would put it to rest by now. 

Opinion | We Might Be in a Simulation. How Much Should That Worry Us? – The New York Times:

The conclusion seems inescapable: We may not be able to prove that we are in a simulation, but at the very least, it will be a possibility that we can’t rule out. But it could be more than that. Chalmers argues that if we’re in a simulation, there’d be no reason to think it’s the only simulation; in the same way that lots of different computers today are running Microsoft Excel, lots of different machines might be running an instance of the simulation. If that was the case, simulated worlds would vastly outnumber non-sim worlds — meaning that, just as a matter of statistics, it would be not just possible that our world is one of the many simulations but likely. Chalmers writes that “the chance we are sims is at least 25 percent or so.”
