- throwawaymaths 4y agoIirc the story was fb messenger was written in Erlang, then they rewrote in c++ because of no trust in erlang (I think that was around when fb messenger started sucking with everyone complaining about bugs -- it was better last I used it 4 yrs ago) then ironically they re-acquired Erlang via WhatsApp. I wonder if they will make that mistake twice
