I can vibecode in Rust but I don't like the result. There are too many lines of code and they are too long and contain too many symbols and extra stuff.

Just compare SeaORM with Ruby + sequel where you just inherit the Sequel::Model class and Sequel reads the table schema without you having to tell it to. It gives you objects with one method for each column and each value has the correct type.

I was happy with Ruby's performance 15 years ago and now it's about 7-20x with a modern ruby version and CPU, one a single thread.

AI is still helpful to learn but it doesn't need to do the coding when using Ruby. I think the same criteria apply with or without AI for choosing a language. Is it a single-person project? Does it really require highly optimized machine code? etc.
