As macguillicuddy pointed out, the point was that the general concept of simulation is indeed unfalsifiable, and we can only ever hope to falsify very limited subsets. E.g. we can certainly say certain things about what features a simulation must have.
It does however not necessarily make a simulation a difference that makes no difference, because if we're in a simulation it is possible that we are in one where it is possible to falsify the theory that we're not in a simulation.
E.g. we could potentially find bugs that reveal telltale signs we're in a simulation, or outright vulnerabilities. It's even possible we could finds ways of "escaping" the simulation.
The problem of course being that you could well devote a lifetime to it and find nothing and it would tell you nothing about whether we're in a simulation or not, so unless you run into some anomaly that hints at it, it'd seem a rather wasteful pursuit.
In reality, of course, chances are none of us will ever see anything to give us reason to pursue that idea, but it's fun to think about. I write short stories about this subject, and I have a long document with headache-inducing scenarios to write up.
