We have never discovered a self-replicating pattern in a random life-field. I once saw > a calculation that showed you would need a computer with the volume within a few orders of magnitude of the solar system to do so (not mass, volume). All the ones we have are intentionally constructed.

Well, per Bekenstein bound, an apple gets approximately 10^41 bits, so I think our universe really has no problem in allocating space for computational resources.
