That's fucking awesome. I'm a math algorithms guy myself but have causal interests in many things. Last I checked there were issues getting the structure and ensuring cell growth was consistent aka some muscle cells didn't start growing into something else. The fact that the body can orient itself in 3D, grow the right tissues in the right place at the right time, and stop is absolutely amazing. Most people seriously underestimate cellular intelligence and the computation going on at a low level. I want to believe the core mechanism is fractal in nature so it's super easy to condense the information required and perform error checking. Also that's there's a general fractal structure to reality would seriously be fitting. Maybe something like the Exceptionally Simple Theory of Everything by Antony Lisi. Some regular repeating structure makes construction so much simpler. It's probably more complex like a hybridization of approaches given particular conditions. It's still dumbfounding that nature just figured it out. Gives one a sense that there's a mind at play at large time scales. Like we're comprised of cells and we ourselves are cells of a large entity. Once again this is a bit pie in the sky x-files I want to believe level stuff, but still.
