Crystal was overall a pleasant experience, which I cannot say for Rust. Although it was probably my fault: 1) for being "rusty" as a programmer myself, and 2) having zero experience with Rust. I want to believe that once you get over the learning curve in Rust development speed becomes much higher. Surprisingly, Crystal seems to be much leaner in runtime size than Rust, with similar performance (although the use case is so simple that even good old Ruby is fast enough). But then again, I feel you cannot beat Ruby in terms of dev productivity.

I've heard it described that Rust allows you to write programs in a specific way. If you try to write them in any other way, you're going to have a very, very bad time, and fight the borrow checker every step of the way. But if you embrace that way of writing programs, it makes it pretty easy, you get really good error messages, and as a cherry on top your program will be provably sound in a way pretty much no other language can guarantee. So it all comes down to whether you're interested in learning that specific way of structuring programs.

  That's true, but then it is not "allowing" or "enabling" me, it is "forcing" me to do it that way. Of course, the Rust compiler is catching a gazillion bugs beforehand, so this is cool: you finally feel like your program will have no bugs once you manage to compile it. Error management through Option values, the borrowing checker... they are cool technologies for a C-like language, but they are not palatable at the beginning (maybe they are an acquired taste like beer?). I am tempted to stretch it a little bit more and see how productive I can become writing Rust code, but also not so sure about the effort.

  The real cherry on top is that you can put "written in Rust. Modern. Fast" on your project description.

I also gave Rust a go (last year? Hard to keep track since the pandemic) but the book I was using was geared to C programmers so I quickly lost interest, though I would like to understand what the hype is about. I think the bit about productivity may certainly be true if you have to use libraries, obviously Ruby has many more available now (maybe forever), but I certainly feel more productive in Crystal now, maybe for things other than the language itself, admittedly. For example, producing a binary makes installation a breeze, and I don't worry about which version I'm running as I point the right compiler at the code; no Bundler now, library installs are sane (at last!); and socially I find the lack of "rockstars" in the main team refreshing, I have no fear of being dissed or dismissed, it makes contributing easier.
