Yeah, it is maybe a bit of a clickbaity title, but I thought it was relevant enough. I tried Rewriting it in Rust and ended up not finding it worth the cost. There was some rewriting in Rails, but indeed, not very much.

I did learn that things wouldn't necessarily be any better if I were to use language/framework X instead of Y.

Edit: I guess I also learned that Rails does so much for you, so you can focus on building a good product. Just gotta make sure you use it as it wants to be used as much as possible.
