I think you may be presuming that every UI that consumes this data is able to display a map showing the bus’s location. We do make real-time bus lat/lng available through our API and lots of clients use that data. But there are other applications where a time prediction is still helpful. For example in many of our stations that serve bus routes, we don’t have the infrastructure (yet) to display a live map but we do have digital signs that tell when the next bus is expected to arrive.

I also work in the customer tech department for the MBTA. We use Elixir and all of our web interfaces use Phoenix on top of that. We don’t require anyone to have experience with elixir or erlang; most of our developers have learned on the job. We look for solid general programming skills and a willingness to learn. We’ve had a lot of success with that strategy so far!
