> Having said that, if you already had Erlang and an experienced team, you wouldn't ditch that for Go. Why do companies do this?

You don't get promoted until you do the new shiny thing. This seems to be especially prominent in Google and the likes. Big companies do not give out bonuses/promotions for those who quietly sit and work with existing, proven stack, maintaining it and fixing bugs. Shiny new things get noticed.

It might also be caused by staffing issues? Erlang/Elixir to this day are pretty niche stacks. It's much easier to find Go developers(or developers willing to switch to Go), than Erlang.
