> It's funny how quickly opinions seem to change. Ruby's popularity peaked during Web 2.0 when almost all new apps were server-side web apps. When smartphones came out and a massive fraction of development shifted over to client side apps, it sucked much of the air out of the room for Ruby and Rails. (And dynamic typing in general. Runtime performance is a fungible cost for server-side programming where you can throw hardware at it, but a hard requirement for client-side apps running on devices you don't control.)
