As a an aside: I wonder if we are hitting a local maximum in terms of programming languages/ecosystems. These days if you want to experiment with some truly novel programming concept (see for instance Unison, Dark, Luna), you have to compete with truly excellent IDEs, Git, excellent code hosting like GitHub, large open source package ecosystems, high quality linters and auto formatters, and other niceties. So if your language/ecosystem can't take advantage of those things (for instance not being traditionally text based), you have a huge cost before you can meaningfully demonstrate any superiority. To do that you probably need dozens of people working for several years, and I don't think the economics are there for it.
