The question we're faced with is whether unexpected events such as Trump and Brexit make it more or less likely that we are living in a simulation. Are they the kind of thing we should expect to see in a simulated universe?
It does take time, or rather I ought to say money, to go racing... Racing is expensive and whilst one might think "Gosh paying for simulator time when I could be on a track" is indeed true, but mixed in with a planned racing or track time schedule, the simulator will save you money in the end.
For one thing, discovering the universe was a computer would also mean the end of death, since there would also be no life of which it would be worth speaking. This is a significant improvement on life as we find it today.
