While an interesting thought experiment, no one is proposing that you will get self-assembly of an organism by expressing 10,000 genes. We really don't know wha

While an interesting thought experiment, no one is proposing that you will get self-assembly of an organism by expressing 10,000 genes. We really don't know what the beginning steps of this process were - since it only happened once (or however many times life arose). Once an organism was made, now it can just express whatever proteins it currently needs, based on lifecycle/nutrients/metabolic requirements/etc.
