Whatsapp is indeed a bad example for 'Code monkeyism', since it's quite the opposite. The Whatsapp guys were smart enough to think about using the right tool for the right job in the first place, i.e. stuff like Erlang - which has been tried and tested for scenarios like this for decades - and applied it to a modern infrastructure. Twitter OTOH was built with Ruby on Rails... That's more like a fitting example. :)
