It's the runtime and tooling. Personally, I've largely stopped using the JVM ecosystem and it has nothing to do with the languages. Start up delays killed applets and have always limited command line tools. Now the same startup limitation is afflicting cloud functions. Memory management has always made running JVM processes in a multi-tenant environment complex (from desktop apps to kubernetes pods). The JVM is great in so many ways, but gets extremely complex if you want to do anything the runtime authors haven't prioritized. Maybe GraalVM will change this? After literally decades of waiting, I'm skeptical. /rant Typescript is still javascript and single threaded. Python kinda has types, but most libraries I used don't. Go's popularity is an indictment of every other language ecosystem. It's not better, just less bad.
