In a dairy barn full of content cows, autonomous robots handle milking, feeding, and cleaning, allowing farmers more flexibility and improving cow welfare. With robots, cows produce more milk and more comfortable lives. Could this be the future of sustainable farming?
I evaluate basically all my food with what I call “hotdog math”. my wife hates it. my local gas station sells hotdogs at 2/$1. the free toppings can push the calories count near 550, but I know nothing comes close, so I round down to 500. milk beats oatmilk on hotdog math, and carries a wider diversity of nutrients, to boot.
Your wife is right to hate it. It’s rather shallow and narrow-minded.
That aside, if calories-to-price is your metric, are you growing your own food?
it’s a metric for food I buy, and anything less convenient that a gas station hot dog that costs now power calorie is a hard sell. I don’t live on has station hot dogs, but they are, in my opinion, a good standard for convenience food value.
I also drink soylent, which is only like half as good as hotdogs, but the nutrient balance is incredible.
my wife says my spreadsheets are how farmers feed cattle.
Cow milk is usually only cheaper because of subsidies, otherwise it would be much more expensive.
I don’t know how this can be verified, nor does it matter at the point of sale
