I don't see why this requires not having dependencies.

Yes, new languages try to create a new ecosystem. I think this is a bad thing - we already have too many of such - often somewhat isolated - language ecosystems. But I also do not think we need new ecosystems, when we can evolve the existing one. I have seen C evolve quite a bit over time, so the idea that we have to create new ecosystems to solve problems is wrong in my opinion. C evolves very slowly, which means that some things need more time, but I also think that it is generally a very good thing that it evolves slowly.
