It sounds like you haven't worked with many startups which is where Rails has been the goto option for a very long time. Rails is a framework. Go is a programming language. Show me a Go command line which sets up a fully-baked MVC app complete with data model, migrations, CORS, caching, asset pipeline, mailer, mailbox, chat(Action Cable), job queue and a Hotwire equivalent. While you're baking all of that yourself I'm launching our MVP. There's Buffalo but you compared Go with Rails so I assume you meant rolling your own using just the Go standard library.
I think that’s as far as the grand scheme of a project goes, coding productivity is a myth.
Can a python or ruby dev bang out Advent of Code faster than I can in zig or rust? Sure. Is advent of code representative of a multi-year long business system where coding is 15% of the time cost at the high end? Nah.
When you look at the actual bills and where the actual time goes, spending time on optimizing the code pace of a MVP is simply not valuable. You’re saving a small percent of a small percent of time at the beginning to accept using languages that are not know for their steady state support ability.
Yep, agreed on all accounts. People simply love their languages and will point out any area they "win" at, even if it's inconsequential and not at all important. And that's happening a lot, including TechEmpower benchmarks, speed-to-first-MVP, and many others.
