Grass is nutritionally poor. The reason we are smart in many ways is due to our varied diet. Even if we had evolutionary gone in that direction we would be dumber. Eating grass is a specialisation.
Also, we would not look like we do. If you look at the digestive track of a horse or a cow, you will see that they are longer. Carnivores have the shortest and we as omnivores are in between. Being an omnivote is a good thing and in the end, we can get more nutrition by hunting and gathering than by grassing.
Worth noting, while individual cows’ behaviour and preferences vary greatly, the time spent feeding and ruminating usually adds up to 4-7 hours a day. Our society would be were we are today if we spent 7 hours as a species eating grass in order to make ir worthwhile.
Evolution can only evolve so much within an existing animal especies in order to specialise or fit in a survival niche. Hence you do not see sea crabs that can fly or flies that live in the bottom of the sea.
