As engineers, we love code-reuse. We DRY up our code to avoid repeating ourselves, we refactor to make our code cleaner, and we pull in external dependencies for common needs like background jobs, unit testing, metrics, retries with exponential backoff, etc. etc, etc. However, external dependencies are a liability, a ticking time bomb waiting for another xz-style attack or a crypto coin miner attack. In a post-AI world, it's hard to imagine why we wouldn't invest the time in building and maintaining our own tools that we understand fully and are built with our local problems in mind, not some generic abstraction. Elixir already ships with everything you'd need to write a good-enough async job processing system like Oban, test helpers, and integrations with external systems like prometheus. The way is lit, the path is clear, we require only the strength to follow it...
