China famously now has "dark factories" where everything is automated, so lighting is not needed.
Guess this means we're about to have "dark dairies" where cows can be kept chained up in perpetual darkness, with robots doing the absolute minimum required to keep them alive, pregnant and producing milk.
I know this is not a particularly pleasant thought, but I'd like to hear counterarguments about why this wouldn't happen, since to me it seems market pressures will otherwise drive dairies in this direction.
(For what it's worth, I'm not a vegan, but a visit to a regular human-run dairy sufficiently confident in its practices to conduct tours for the public was almost enough to put me off dairy products for good.)
