I am posting this in the open thread because I assume that somewhere in the depths of posts and comments there is an answer to the question:

If someone thought we lived in an internally consistent simulation that is undetectable and inescapable, is it even worth discussing? Wouldn't the practical implications of such a simulation imply the same things as the material world/reality/whatever you call it?

Would it matter if we dropped "undetectable" from the proposed simulation? At what point would it begin to matter?
