「Railsでまだ消耗しているの？」─僕らがRailsで戦い続ける理由─ / Why We Use Ruby on Rails

2017年12月9日に行われた Rails Developers Meetup 2017 ( https://railsdm.github.io/2017/ )での発表スライドです。

なぜRailsを採用するのか──あなたならこの問いにどう答えるでしょうか。Railsは遅い、RailsのRailには乗りたくない、Ruby/Railsの黒魔術が怖い…さまざまな批判の声も聞こえてきます。本発表ではなぜ今Railsなのか、”Why Ruby?” “Why Rails?” という２つの観点から考えたいと思います。
