No, I’m not. I’m really not understanding what this straw man is that you’re arguing.
When bosons were predicted, the method by which they would be measured was also predicted. Just because it took 40 years to do that doesn’t mean that they were untestable. “Unobserved” is not the same as “untestable” which is exactly the distinction that you’re missing with the simulation idea.
I’m not saying anything of the sort. You suggested that it is possible for our reality to be a simulation where the creator of said simulation is actively making changes. Those changes would have to be observable by the people inside the simulation. You then retreated to the idea that the creators are perfect and simply stop the simulations where those changes are detected. Epistemologically, that idea is both untestable and unobservable because, according to you, any simulation where either of those things were true would have been stopped. That makes it impossible for our current reality to be one of those because it has not stopped and, again, any simulation that is indistinguishable from physical reality is pointless to discuss because it’s non-falsifiable. It’s just like the one day old example I’ve given several times now that you keep ignoring and never addressing.
