I was a Rails consultant for about 7 years. Then, I switched to Phoenix - really out of just curiosity. Since then, I've never looked back. If you never believed in "Simple is better" philosophy, you will after using Phoenix. The development time is shorter, the bugs are far less since you catch them at compile time and the development experience is unmatched. Oh, and did I mention performance? You can get insane performance just out of the box.
I wouldn't describe LiveView as simple, necessarily. It makes for a great demo, but in my experience it complicates simple things in lots of subtle—and occasionally pernicious—ways.
Whilst you can use Phoenix without LiveView, this is becoming increasingly difficult as the Phoenix developers have clearly decided that LiveView is The Way.
