This is a horrible development. The video shows how they'll make them smaller than what you normally get, precise measuring of ingredients means there will be no human element adding a little more here and there.
Also, there is a well known trick that if you want to get more you order half and half on the protein (1/2 chicken, 1/2 steak) and you end up getting more because of how they slop it on (3/4 chicken, 3/4 steak for 1.5 times the protein). This will end that!
