Perhaps, but y'all are reading something into his comments that I didn't. He even mentioned that it would be unpopular to give up beef and that US cattle produce less methane gases than there counterparts in Africa. Sounds as though he is hedging his bets that it would ever happen. Beef is a commodity...if prices go up, more people raise cattle. If prices go down, you have fewer cattle that go to market. I remember going with my grandfather to sell cattle and him figuring how much to sale or not to sale based on the price he could get. Not sure there is any way to change that.
What annoys me most is the continued pattern of the rich elite lecturing about things that they themselves have zero intent to implement in their own lives. Bill may fully believe we need to shift to synthetic beef, but he has zero intent to make that shift himself. Unless he's already on a 100% synthetic beef diet, then he needs to clam up.
