My "side" take on this is that as long as reimplementation is considered an urgent activity with each new language, we may be privileging languages that are actually better for rebuilding things that are already well understood over languages that are better for "feeling our way through problems". I'm not 100% sure of this point, but it feels at least possible that features that make a language good for reimplementing a problem with the structure known in advance might be awkward for exploratory work. I've built a bunch of stuff recently where I had NFI what I was doing as I went along and had to tear up vast tracts of the data structures as I went; it was good to have the fairly loosey-goosey typing of a mix of C/C++ and (effectively) asm to do it (while still being able to see performance levels of aggressive optimization, which was also part of the goal).
