Oh no, not another ‘Is Rust better than Go?’ article. Seriously, haven’t we all had our fill of these comparisons by now? But before you sigh in exasperation, hear us out!
code that’s been written today has been made obsolete by a language feature in the latest nightly build
I mean couldnt you say that about any language? There’s lots of old C code that’s obsoleted by features in C11. There’s lots of stuff written in python today that’s obsoleted by stuff in the 3.13 alpha. It’s just kinda how things go.
Doesnt the edition system prevent this from being too big of an issue anyway?
Sure you could say it about “any language,” but I think you’re skipping a lot of nuance with your examples: python has notoriously had a long transition from 2 -> 3. C is 40+ years old, and the semantics and idioms of the language aren’t changing from month to month.
I think the parent comment is making the point that the pace of change and evolving idioms/features of Rust means that code you write today may need to be updated in a far shorter timespan than the typical timeline for working code (a few months, rather than several years). The bitrot is just a lot faster right now than other languages.
