That title says it all. There are two people I think of here: Tyler Cowen is eternally optimistic. He may say he doesn’t like something or he thinks something is “not the best it could be,” but he’s rarely “negative,” and never bitter. James Watters, despite a rough couple of decades for PaaS (his life’s work) is eternally optimistic. He only talks about positive things and potential, not bitterness about rival technologies.
