I guess i tend to work on projects large enough where we need to use them
I’ve worked on some very large projects (100,000s of lines of code), and we didn’t have them. We had a DLL folder (this was old school .NET Framework). It worked fine.
You don’t have people doing dumb stuff like importing a whole library for a trivial piece of code.
I try to avoid libraries these days unless it is worth using them.
Im not managing that many libs manually
I suppose you haven’t been burned enough by dependency hell yet.
EDIT: BTW, I am not saying you should or shouldn’t use them. I am just saying that there are drawbacks to using dependency management systems.
