"I’m not really sure what the point of thinking about SA is. "

I agree. A few paragraphs earlier, the writer mentions "the pragmatic cash value" of Simulation Theory. I don't think there is any. To determine the pragmatic cash value of a hypothesis, you ask how the universe would be different if it were true. But nothing would be different if the Simulation Theory were true. If we were living in a simulation, what could prove to us that we were not real? And what would it even mean for us not to be real? If the Simulator entered our world and started to make us disappear one by one, we would experience it as a change in our reality. Because the simulation -- complete with the laws of physics and biology, the Homeric epics and the 19th-century Russian novels, Bach, Mozart, and Beethoven -- is our reality, a world without them would be a different reality (ie, simulation).

Reality is simply what there is. You can discover whole new realms of reality, But you can't get outside it. If you think you have, you've simply expanded our conception of the real. Which is actually quite an achievement -- but it's not, except as a manner of speaking, creating a whole new reality.
