This is pretty common in corporates too. Shiny new project gets all the attention, funding and management focus. The poor guys left to deal with the day to day crap get screwed over then leave. If they leave too soon its an emergency, if they stay too long they get laid off.

Oh for sure. The last company I worked at did a similar thing and decreed that all Ruby projects would be maintenance-only and all new projects were to be in Golang, despite there being a single golang dev in the entire company (who did not even work in the backend dev team but rather in a "platform" team). Within five months all the Ruby devs had left, so despite not a single Golang project being released yet the company now had nobody who knew how the current system works. Several large outages ensued.

Yeah.. I'm seeing the same thing where I work. Moving from ruby/rails to elixir. No outages, but dev speed is at a crawl. All the legacy stuff just gets ugly patches.

There was zero need to switch because even though elixir/BEAM allows for a pile of processes, postgres does not.

If I had to guess, the switch was made because someone saw something shiny.
