I think people like you and I might be posting about this for awhile. I actually had more thoughts on this after I posted, but I did my four posts for the day. I might post about some other things tomorrow.
Time. I have some thoughts about that to share. Just to cover the concepts of like IF the machine is turned off...
Then the discussing of if we are a simulation... how do we see outside the simulation. I want to do some thought experiments and crazy brainstorming on that. :)
We can endlessly speculate/hypothesize off of this single concept.
Yet as the Deists tend to say. There was a creator (whoever started the simulation), now observe the world around you and use reason.
It ultimately may not be important that we are a simulation. Yet it sure is fun to think and talk about. :)
