More like a few decades of extreme churn. Hey dude are you using Crate #43? No, thats dead on github. Try Crate #999. No dude that uses a diff async runtime. Try Crate #888. No dude, that has protest-ware on it and the boss complained. Try Crate #888. No dude, that has incompatible dependencies. Try Crate #456. No dude, that lib causes "fearless concurrency" deadlocks with async. Try crate #999. No dude, that has a gazillion macros and compilation times approach the heat-death of the universe. Try Crate #666...and the story goes on.
Remember when python was simple? And you just had setuptools? Popularity breeds complexity and fragmentation.
