It’s a fallacy when making ten year predictions to assume nothing will change in order to lead to the prediction. Presumably for the idea of plant based diets to dominate, there will need to be an available substitute for meat which is competitive economically and in taste.
It might be enough to force near prices to include their environmental impact. I think that's what the post says about meat becoming like caviar. So it would still be available, just way too expensive for every day meals.
Jacking up meat prices would upset a lot of people. Meat-substitutes would have to be cheaper than they are now. Food By Products are already used in meat as filler. Like ground beef and hamburgers have cereal or soy in them.
