As a dev that hasn't touched Ruby in his time yet, could you expand on the productivity differences you've seen between Java/C# and ruby devs? I totally buy that a language like ruby can be more productive, but a 3x difference is wild. Have you found that RoR is really just that much more productive than say, Spring or Asp.NET?

(Ruby -> Rails) As one that switched into Rails after a decade of web dev, IME its the batteries included nature. You can't compare Rails to Go or Typescript. You compare Rails to language + all the standard libraries people use. The trick with Rails is _most_ of those choices are baked into the framework, so e.g. 25 rails dev's will know _mostly_ the same exact set of libraries walking in the door.

Personally I absolutely hate it, and regret taking a job in it. Its the first language ecosystem that made me realize yes, apparently I really do care a lot about the language(s) I work in (had prior exp in php, python, java, Go, and Typescript, and enjoyed most of them). But I wouldn't knock anyone for using it, especially if they can hire experienced teammates in it or generally find the approach (typeless, convention over configuration) appealing. It's definitely a great choice for a web product if the team(s) will stick with it over time. I'd happily manage a team using it at this point, I just don't want to write it anymore.
