3-4 years ago I was convinced that Rails was in its sunset years. JS had all the energy, Ruby conferences were disappearing, and it seemed like there was no new open-source development happening: we were all just using the same gems we'd used for years.

I'm happy to say that I was proven very wrong. New conferences have sprung up, over-the-wire is trending well against SPAs, and there's been a ton of new features and approaches that have kept Rails and Ruby very relevant to modern development.
