I am writing a lot of the code that might be found in libraries for my project; I'm doing it mostly because: third party, open source libraries really need to be treated as hostile code until they're vetted... and then will continue to need vetting with every update. For a fair number of uses cases, writing the library is less than or as labor intensive as a good audit and writing them in Elixir tends to be pretty simple. For the larger more complex and essential libraries, there are solid, fairly well endorsed packages out there (they still need vetting though). Of course, there's the option of taking an appropriately licensed open source license and making an internal fork... not expecting to really receive updates from upstream after the point of departure.
