I guess it boils down to whether or not we're willing to accept infinite regress or not. Of course, if not, one must necessarily accept that reality 'comes from' nothing.

Although I'm a VR developer, I can't believe it's "all turtles all the way down" :@)

Actually I've been working on a theory to define randomness from complete uncertainty, without the "fair coin" metaphor based on constructivism, which is deterministic.

UDASSA (http://fennetic.net/irc/finney.org/~hal/udassa/) is the closest thing I've seen to a believable idea about how reality could come from nothing. It's basically a more specific version of the mathematical universe hypothesis.

If you're trying to make a deterministic theory of physics and eschew randomness from the world, then you're going to run into big problems from quantum mechanics. The idea that results from random quantum interactions comes from hard-to-measure factors in the world that we just happen to be uncertain about is called a hidden variable theory, and Bell's Theorem shows that those theories are incompatible with the principle of locality. Though there is one popular local and deterministic interpretation of quantum mechanics that avoids this issue: the Many-Worlds Interpretation. I wrote a post in another thread recently that's relevant: https://news.ycombinator.com/item?id=22845499.
