No, it sounds like you just have a mostly "I write code that goes on servers" type job, and haven't been burned by the issue of older binaries, that won't work

No, it sounds like you just have a mostly "I write code that goes on servers" type job, and haven't been burned by the issue of older binaries, that won't work with new libcs. This is a real problem with Linux (not MacOS or other BSDs from what I understand) because it doesn't have a stable ABI (the ABI is basically glibc). It's a design choice, and a pain in the ass for people who want to distribute things as binaries. Which, well, it's not something I do, but, it has burned me using other people's things. Could docker/containerization solve this problem? Yes, in the same way that a shotgun would serve for eliminating mosquitoes...
