A lot have already been said about it: +Lisp Lost the train of microcomputers. They were "toy machines" that needed low level programming like assembly or forth or later C to do anything remotely similar to what Mainframes could do. +Common Lisp is a mess, a compromise, like Deutsch (a language created to take something out of every variant dialect), designed by committee language. Better (opinionated, created by a person) alternative Lisps exist, like Clojure. +Lack of (affordable, easy to use) Visual tools to develop, like Visual Studio. No. Emacs is not easy to use for newbies. Visual structured editing for parenthesis have existed for decades now but those tools were not available for normal PC and even today are very expensive, as the market for them are the companies that bought the expensive Lisp machines in low volume. +Lack of access to the C libraries. Do you want to use anything modern like "dear imgui", iOS libraries or whatever? Bad luck. +Competition catch up. Other languages copied(badly) the Lisp ideas, lambdas and real macros, functional programming. IMHO they did it wrong, but they are good enough for most people, while not having the problems of CL, like being able to use the C libraries as python and Lua can. +Other Lisp are working fine. Clojure for example can use the java libraries or even some versions the C Libraries.
