I didn't see it here, but one of the points that doesn't seem to be expanded on too well is that despite liking Rust, I wouldn't use it for a basic web server in a startup environment either, mainly because the whole environment around web stuff is too immature in my experience. Ruby on Rails certainly isn't perfect, but it's a highly battle-tested web framework. It's been so widely used for so long that you can have high confidence that you won't run into any bugs that will require digging into the guts of it. You can write code against it and be highly confident that any bugs or misbehaviors are in your code, with difficulty of finding and fixing dependent only on how good the code you've written is. With Rust, I don't think that's the case. The DB and web server related libs just don't seem to have that much manpower behind them, and haven't had big complex services built on them in production for years. If you want to do anything mildly complex, there's a good chance you'll have to dig into the guts of these to figure out what's really happening or to resolve some weird bug or add a feature. That'll require a lot of skill, even if the code you're actually writing is mostly straightforward.
