The Arc language (which runs this site) is a remarkable attempt to "fix" what went wrong with CL. It lacks a decent runtime and native code compiler (it offloads everything to mzscheme, the way clojure did to JRE) but it is already more than a proof of concept. The problem is that there is no more DoD or other grants for creating new Lisps anymore (particularly due to Java mass hysteria and prevalence of packer's mentality). BTW, making something similar to SBCL (everything written in itself, except for a tiny kernel written in C) for Arc (a core language, without the kitchen sink syndrome) is of moderate difficulty compared to meaningless piling up of more and more of Java crap.
