>>14180107>>14180167See, unlike the other anon, I get what you're trying to say. The human body is essentially just a very complicated biological 3d printer.
It's true, printing a gear doesn't impact the function of a 3d printer, but that analogy breaks down.
The human body can very readily alter itself, given the right genetic modifications. How else would it self-regulate otherwise? How does half of all our medication work?
Of course, if you mutate stuff randomly, you'll more than likely just create tumors, potentially cancerous ones. But it would be possible to alter your physiology through just genetic meddling alone, given the predictive power to model the effects and the means to implement them.
