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.

That's the only thing RoR wins at: speed of delivering first MVP.

Once you get into areas where companies don't die if they can't deliver a demo next week, RoR is not at all impressive or even consequential.

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.

It's not a complete myth. But I'd agree that it's overblown and overly touted.

Oh gosh, stop it.

I skip Ruby hype but I know RoR and I use Golang professionally to build microservices serving Fortune 10,50,100,500, whatever and I wouldn't use Go to build a web-application.

Golang for microservice that relies on other microservices are great (i.e. my Golang service doesn't handle authN/authZ, but another service does), Golang for monolithic web-app that has to handle db migration (yeah I know something exist), implement multiple crud objects (remember, Golang microservices typically has smaller context and challenges than a medium size web-app) is pain in the ass!

PS: cut my teeth in Java servlet/jsp, moved on to Spring Framework+GWT, skipped RoR went straight to JS and ended up in Golang for the last 5+ years. I'm not Rails worshipers but I'd probably pick Java Spring ecosystem over Golang for monolithic web-app.
