> I think the big problem is that it is difficult to scale lisp projects with inexperienced developers (loses to java) and is not zero cost (has a GC, is often interpreted; loses to c, c++ and now rust). i think scalability problem is a bit overstated. the biggest issue with lisp becoming popular is that it doesn't have a large user base and is not a new language like rust. however despite being old, common lisp /still/ has so many 'novel' things in it that in metrics of programmer ergonomics and programming user interface make common lisp a big winner for me. as regards zero cost, lisp programs can be made arbitrarily close to being zero cost, but here be deamons.
