I don't agree, or I didn't get your comment. I'm a software engineer and I strongly believe that if every humans on earth worked all together with a single goal in mind, space exploration and conquest, instead of spending millions on wars (as an example) we would already been on Mars, or close to it. I kinda feel ashamed when I think about it, I would prefer to work into something which have a bigger impact on the humanity future, and that what I want to do later in my life. Musicians, clowns, video games, movies, are all entertainments, it adds pleasure into doing things but don't contribute in the to the goal of a greater knowledge of the universe. (you could argue that if X wouldn't have listened to Y song he wouldn't have discovered Z, and I would agree).
