alt Hacker NewsThe phenomena you're describing is why Cobol programmers still exist, and simultaneously, why it's increasingly irrelevant to most programmers
The killer feature is ecosystem: Easily and reliably reusing other libraries and tools that work out-of-the-box with other Python code written in the last few years . There are individually neato features motivating the efforts involved in upgrading a widely-used language & engine as well, but that kind of thinking misses the forest for the trees unfortunately.
It's a bit surprising to me, in the age of AI coding, for this to be a problem. Most features seem friendly to bootstrapping with automation (ex: f-strings that support ' not just "), and it's interesting if any don't fall in that camp. The main discussion seems to still be framed by the 2024 comments, before Claude Code etc became widespread: https://github.com/orgs/pypy/discussions/5145 .

The alternative is when you run a script that you last used a few years ago and now need it again for some reason (very common in research) and you might end up spending way too much time making it work with your now upgraded stack.
Sure you can were you should have pinned dependencies but that's a lot of overhead for a random script...
Most programmers aren't writing scientific software, which you can tell by claims that nicer f-strings is a pressing concern.
