"Lisp was created to make it possible to solve ... problems so complex that holding back any power from users would have rendered the result useless. The designers of Lisp went all in to provide the best tool set they could imagine for solving the most complex problems they could imagine, and mostly managed to leave egos on the shelf while doing so. The reason it isn't changing much is because it's a masters tool set, forged from an ocean of experience; the types of software people build in Lisp change at least as fast as the rest of the world."<p>I'm a very long time and continuing lisper, but every assertion above seems to me either false, so grossly overstated as to be effectively false, or true of many other languages, and therefore not interesting qua lisp.
