Not exactly about codebases, but I believe the universe operates like a cellular automaton (CA) at its most fundamental level. (Idea originally from Stephen Wolfram.)

A CA, if you don’t know, is a simulation in which a cell in a grid evaluates nearby cells and returns a value based on what it finds and the rules given to it. What happens next is called ‘emergent behavior’, and in some ways mimics physics and even primitive life. In fact, many physics models use CA already.

What this means to me is that there is ultimately only one type of energy/matter, and that everything we can detect (quarks, photons, atoms, etc.) is made from the same ‘stuff’, and that nothing is truly random… it’s just that we lack the tools and models to predict what happens below the smallest observable scale.
