text: Like i said it helps with alot of differnt things, the author says, " hold on, can we acually "calculate" emotions." yes we can, its a "smart computer" & its like a person. I say its like a person because, say you see your friend and he/she has a frown on her/his face. You auctmactly know theres something wrong because he/shes frowning & thats also what the computer is bacislly doing.
