Heh, funny. I've actually seen someone else (a scientist... I think) suggest that we may be living in a simulation fairly recently and apparently there are experiments underway to test whether the theory holds water or not.
Though I'm not sure how they'd test for something like that.
It's all very interesting, obviously, but I don't think it will affect us much. At least not in this lifetime.
The implications of the idea are funny. Who is to say it's not a "matrix" ordeal and there are simulations within simulations within simulations. Actually, I recall a cartoon recently mocking this idea also, multiple times actually.
Funny, I used to think something like that also. When I smoked pot. Maybe I can share some of my other theories with Elon Musk.
