If we're code, and it for all practical purposes is indistinguishable from what we consider reality, what does it matter? Though if we knew, and had a way out, we'd then have a choice to make if we're satisfied with that or want to try to see if there is another layer outside that again. Of course, if we can't find an "escape" it isn't proof that there is nothing outside.
