text: An example from the excerpt was detecting if we can see if a human is faking a smile or not. I get it, it would be outstanding to read everyones emotions, but at the end of the day its about what that person that is feelng a certain way feels about expressiong their emotion or not. If a human were to force a fake laugh and a computer shown that that was indeed a fake laugh, it would make the person who thought they were really laughing feel stupid, or upset. I am not saying lying is good, but sometimes its best to fake a smile for a better outcome of any situation.
