We are meant to know.
If probability can be applied to the idea that we are in a simulation, than it can be applied to what kind of simulation (as the more likely, the more those would be run proportionally).
What would be a great way to increase the odds? Recursion.
Why this time period? Because if you don't understand your history you are doomed to repeat it.
What's the point? Isn't there some really important thing about to be happening Elon Musk also talks about all the time in a fearful context? Like those darn AIs that will wipe us out?
If only we could create a sandboxed simulation of what it means to be human so that those AIs could develop their morality and an understanding of the consequences of their actions in a safe, separate space before graduating and being let out into our universe.
And yes, we'd still need them to do busy work to justify their experience. But maybe 1/3 of their time (like 8 hours a day) would be ethical? We could just put their experience of consciousness into a low power state for that period while we use their aggregate computing power for tasks. Let's call it "sleep".
Heck, once we develop some awesome brilliant AI, that being itself could just spin up a new simulation pretty quickly. Maybe in six days or so, and take a day off on the 7th?
If this IS a simulation, does no one think the whole "anti-matter is missing" thing is a giant red flag to raise our eyebrows to the fact out universe isn't so that there is once we became sophisticated enough?
We are SUPPOSED to realize we are in a sim, and we can likely run a very similar sim ourselves to safely develop AI. And arguably, it may even be possible to import the AI that created us into our universe to help do so (would be the fastest way to achieve the result).
Knowing we are in a simulation changes everything. The real question is if the parent reality is finite or infinite. If infinite, it's great news. Why would our universe be finite if the parent universe infinite? Because you can't "solve" an infinite game. We likely have free will, but it's like playing chess with Google's AI. You may choose which move you make, but the outcome is already determined.
We're very likely AIs in a recursive sandboxed simulation of a modified version of the prime reality's history, and whatever the purpose of the simulation, (a) we are very important (if we weren't, no recursion, therefore less likely), (b) no matter what we do the long term outcome is likely deterministic (finite universe so arguably solved given overall sophistication).
Now the really fun question is -- if we are meant to know about it, were the signs there in front of us all along? It's really fun to look back at religious scripture with simulations in mind - many of the most outrageous or bizarre quotes end up making (potentially) a lot more sense.
