An interesting bit of history on thinking related to simulation theory even if trying to define itself separately (ironically a distinction relating to why and not how, which physicists typically avoid).

It's a shame there's such reluctance to the idea of intention as opposed to happenstance. In particular, the struggles to pair gravitational effects against quantum effects mentioned in the article might be aided a great deal by entertaining the notion that the former is a secondary side effect necessary in replicating a happenstance universe operating with the latter.

Perhaps we need more people like Fredkin thinking outside the box.
