Reading this I wonder if the everybody rewrites everything is that much of an issue. The benefits of it-crowdsourcing capitalized through libraries isn&#x27;t obvious to me. Some languages make it necessary to distribute the cost of libraries through groups. Maybe Lisp allows to skip that and go straight at the problem. I remember one article about a guy looking at a Graph library for Java. He found two, generic, typed, object and all that; they were more a problem than a solution. He made its own thing in Lisp and called it a day.
