alt Hacker NewsI'm happy to see v4.0, but 2025 was the year I switched from Ruby to Python after gradually drifting back to it more and more. The tipping point was when I had Claude Code automatically convert one of my Ruby projects to 100% Python - and after that, I just had no Ruby left.
I spent over a decade enjoying Ruby and even wrote a book about it. At this point, though, Python has won for me: fastapi, pytorch, langchain, streamlit, and so on and on.
It's a bit sad, but I'll always remember the Christmas gifts, and the syntax that is always so much better than Python.

This year I also switched from Ruby to Kotlin on my hobby/light commercial backends. I just can't stand the way Ruby is not statically typed, and the resulting insecurity around if everything is actually doing what it should do. Kotlin gives me joy, and performance is actually better (trading memory requirements ofcourse, but that's not a big problem anymore). I still love Ruby, but only use it for simple scripts now.
Just by how much better the editor/IDE support is with Python it is a change worth to do.
I just can’t stand the excessive dynamism of Ruby. I understand some people prefer/enjoy it, it’s just not for me.
Langchain? I tried using/learning langchain then I found out that it was evolving so fast that even the latest ai models didn't have even remotely up to date information on it! Not to mention the hundreds of Google search results for ---- why do langchain docs suck? I finally switched to haystack and I have been really happy. (Don't work on corporate ai software this is just for personal use)
You should try Falcon too.
Used Ruby for a decade, knew about it for more than that. I still sometimes use ruby syntax to communicate ideas with friends and colleagues.
For me, the killer feature of Python was the typing module and the intellij pycharm community edition being free and RubyMine having a subscription fee.

It's telling that your reasons for switching are all features of Python's ecosystem, not of the language itself. A lot of developers are moving to Python because of its libraries, and in many cases they don't care for the language at all.
That's causing a problem for Python: many of these developers who'd rather be using different languages seem to want to morph Python into their language of choice. The result is that the Python language is pulled in many different directions, and with each release gets increasingly bloated and strays further from its foundations.
Ruby, on the other hand, has a community that's mostly made up of people who actually like the language. That allows it to do a much better job of staying true to its core philosophy.
