Are Dairy Robots the Secret to Happier Cows and More Efficient Farms?

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?

My milk ranking:
Almond < Dairy < Soy < Oat
I rarely drink any milk at all, but when I do, it's gotta be oat.
(Also not a vegan, but that doesn't have anything to do with my taste here)

if calories-to-price is your metric
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.
