You're comparing a systems oriented barebone low level programming language to a very (maybe the most) high level framework on top of a very (maybe the most) high level language.

I'm not a fan of Go, but that's not the thing to blame here. Using Go for a "CRUD" application is a terrible decision from the get go.

Go is not a low level language. It does pretend to look like C but places at the other end of abstraction spectrum, even if it doesn’t seem that way.

I’m not blaming and I fully knew what I was getting myself into. In the end it worked out and successfully launched etc. Just took me longer and had a learning curve that made me a better developer too. But had I wanted to just launch quickly from a business perspective Rails would have been the way as I already knew it. I still to this day like the simplicity and speed of Go. Like every year or two I come back to Go and try to get the dev experience for my own framework right with Rails in the back of my mind but it’s tough and more of a boilerplate than a framework.

That experience has likely made you a more skilled developer, though.

I'm going through the same path right now, building my own product, and while I do indeed feel like it taught me tons, I don't want lessons, I want to get a business off the ground!
