pnpm is the new hotness. ;)
In python land, uv (for project) and pipx (for CLI tools).
Package management for languages owes its heritage to CPAN, which then, in turn, owes its lineage to StopAlop the first package manager written about 1992, which inspired dpkg. Now there is nix which cuts across system package and configuration management. Perhaps in the future or soon LLMs will be able to rewrite hot sections in other languages and repeatedly benchmark various implementation approaches in a generative manner.
