10+ years of lambdas, but you can still tell from new code that the language used to not have lambdas. Plenty of code is older than that too.

The annotations are static, yeah. That's one advantage. I would still rather not do that. A lot of people were happy not to need that anymore in like NodeJS.

I mean, there are bad developers in every language.

And old code continuing to run 10 years later is a huge value of the platform.

Any company that's 10 years old will have code that's 10 years old in every language they use. And every language has some flaw that was "fixed recently" but that's not relevant in a mature codebase. Like "Python packaging is fixed now with uv" no it's not. And especially anything to do with threading vs cooperative multitasking will stick around.

Mostly old code will keep working, but there are exceptions like Python 2->3 breakage that deserves all the criticism it got.

Yes and with Java they’re the ones still prioritizing annotations over the options built into the core language.
