Nah, not like it is in Rust. For the vast majority of projects, serde makes parsing / serializing something they don't even have to think about, without having to sacrifice type safety to get there. Until you experience that in a large project with a lot of moving parts and developers, it's hard to appreciate just how many developer cycles you were wasting before on stuff that can be totally automated. It's format-agnostic, it's really fast (not the absolute fastest, but fast enough for most situations), it's insanely customizable for even the weirdest use cases, it's absolutely everywhere, it incorporates proper error handling, and adding it to your own types is trivial.
Is there any actual reason something like serde couldn't exist in other languages? None that I know of, but it doesn't, at least not when you consider just how pervasive serde is in the ecosystem (almost every library that stores things you want to serialize will have it). I really hope every language can standardize on something similar; it just makes development so much nicer and faster when you don't have to worry about this stuff.
