But does it though?
I've just taken a new job writing primarily Java whereas I was previously writing mainly python and typescript.
One of the first things I've noticed is how dead Java's ecosystem (Maven central) seems in comparison to other ecosystems like PyPI, NPM or Cargo.
(Also side note: I've published packages on each of these registries and the publishing process for Maven central is comically terrible! This has to be discouraging people from contributing to the ecosystem.)
