I agree the robot is optimistic.<p>From the tiny amout of reading I&#x27;ve done cows eat hardware - nails, screws, and bits of wire that are accidentally left in feed troughs, or bits of wire from tires that are left in fields for some feed product.<p>Many cases of hardware disease would be a oided if there was some concentration on keeping those safe for cattle.<p>But maybe I&#x27;m guilty of armchair farming.
