I spent ~16 years with Ruby (as a non-primary language for the first 5 years, but then as my primary for the remainder), from ~2006/2007 til 2022/2023. I had a couple of hours free to spin up new personal project this morning. At first I was going to default to Python since I use it heavily at work. On a whim, I decided to see what Ruby 3.4 has to offer since it's been a few years. I am very happy with that decision. I really miss Ruby the language a lot, it's such a joy to work with.
Ruby is still a joy for me, too, and Rails continues to evolve while providing solid best practices as the default.
A side effect is an increased intolerance to agony, boilerplate verbosity, complexity. I look at the JavaScript world and shudder.
Also, Ruby being as expressive as it is, describing things to an LLM is not really a timesaver over writing the code myself.
