Have you had an opportunity to look at Julia? It seems that there is some overlap in what can be achieved - with some obvious differences: as I understand it you had a lot of c++ - that could probably (today) be linked from julia, but not "integrated", starting from a green field with Julia, ideally one could do most things in Julia - maybe with some help from rust. And Julia is not a common lisp, obviously.
But in merging a high level language and the love, it seems Julia has been successful in getting a lot of real-world, "all Julia" libraries, with "sufficient" performance.
If you were starting over today - would you still prefer to build a common lisp with close integration to c++?
I did choose Common Lisp over Julia - I started learning Common Lisp in 2013 and Julia started becoming something around 2012.
I did so because of the permanence and the demonstrated expressiveness and power of Common Lisp. Common Lisp has been around for almost five times longer than Julia, and Common Lisp has demonstrated again and again that it is capable of solving hard, poorly understood, real world problems in a lot of domains.
Fun fact: Julia bootstraps off of an implementation of Lisp. Furthermore, most compiled languages are translated into an abstract syntax tree (AST) as part of compilation. Lisp S-expressions are a text based AST. So I can make the argument that Lisp is as close the "One True Programming Language" that we have. :-)
I'm doing chemistry - that's fundamental and timeless - I find it maps beautifully to a fundamental and timeless language like Lisp.
