A few years ago, I remember that all these articles kept popping up about people switching from Node.js to Go.
Now it's funny because fairly recently I read a well thought out article on HN encouraging developers to dump Go for Node.js... These days you hardly read anything about Go at all. Not that there is anything wrong with it, but reality caught up with the hype and it's no longer pretending to be a silver bullet.
Right now Phoenix is pretending to be a silver bullet, but it's really not.
