Java itself has improved a lot taking inspiration from Scala and other languages itself and adding a lot of features (streams lambdas etc). Worth mentioning Kotlin, Scala and Clojure also improved and changed _a lot_ in recent years and so did Go and Rust and other "new" languages that aren't 30 :] Nothing would make me happier than to see JavaScript and C++ abandoned (two of the most popular programming languages and the two I use the most except Python probably). However that would require a lot of work to accomplish and such huge undertaking is usually done a lot more incrementally. Doing it in a "big bang" fashion would be quite a lot of work. That is, JavaScript and C++ are very different than they were 10 or 20 years ago - not just in terms of tooling but also in terms of the language itself.
