Personally I love SPAs and would still use them all the way instead of Django/Rails. The problem with server-side rendering is you need to start duplicating all the code the moment you need some front-end interaction. Also, I prefer when the interactions are snappy, and having to hit the server on every click to fetch some html feels so slow. I do agree though that building SPAs is too complex and that we haven't yet found the perfect solution.
