I code both in Go and in Rails and that statement is true. Ruby on Rails is 5x/10x the productivity, and that's a very low multiplier, I believe it is higher depending on the kind of application you are building. You can easily make a webapp with authentication, authorization, literally everything in just a couple of days/weeks. This takes years in Go, and you likely will end up with lots of code with questionable quality, as Go libraries for developing a Web App aren't as battle tested as Ruby. I like using Go for tiny services with a defined purpose.
