Isn’t that called a duck?
But actually, if most people weren't so averse to biological organisms, perhaps we would've had computer controlled ducks, rats, hens and other small animals by now.
Why bother reinventing the whole thing when you could just replace (part of) their brains.
Experimentation would be pretty gruesome though.
Seriously. If you've ever watched utility crews installing or repairing underground fiber, and then had moles colonize your yard, there is only one logical conclusion: silly humans, you are doing it wrong.
I've brought near-dead piglets seemingly back to good health by giving them a spoonful of rich compost, almost certain to be teaming with e-coli among all sorts of other microbes considered to be pathogenic.
>Animal poop is full of it, and we don't want that in our food supply.
Animal poop is already in our commercial food supply, especially vegetables as you alluded to. Hell, quite a lot of rat and mice meat is allowed in our commercial meats here in the US.
>Machines don't leave e-coli behind to contaminate our food like biological organisms do.
No, instead machines leave behind oil, gas, coolant residues to contaminate our food and soils.
E-coli is only a problem if you don't embed yourself and your gut with as many other strains of various microbes as you possibly can. If you're HIV positive or immunocompromised, then for sure, wash your fresh food and everything else you ingest, for everybody else, don't worry about e-coli.
oh right, humans can't be property
