Well technically yeah but consider that it takes ~9 months for the product to function without constant life support, at least a few years until majority of the basic functions work and ~15 years until it is fully functional.

Talk about compile time.

9 months is caused by head size to how far you can stretch the exit ratio. In a way, we are born prematurely, to lessen the probability of death in childbirth (for both the mother and child).
