Good post and all nicely put together, but there are a number of other posts on the same topic.
One thing strikes me as particularly pertinent right now though. There is a proposition that if we do indeed inhabit a simulated universe, then it might well end when we become able to set up a sufficiently detailed simulated universe of our own - simply due to the extra processing demands this would put on to the higher level simulation.
Let’s hope not, because if so tomorrow could be doomsday… It's No Man’s Sky release date on PS4/PC - 18 quintillion planets! ;-)
hehe that is an interesting observation! :)
