And most are too focused on learning whatever slop the industry wants them to learn, so they don't even know that it exists. We need 500 different object oriented languages to do web applications after all. Can't be bothered with learning a new paradigm if it doesn't pay the bills!
It's the most intuitive language I've ever learned and it has forever changed the way I think about problem solving. It's just logic, so it translates naturally from thought to code. I can go to a wikipedia page on some topic I barely know and write down all true statements on that page. Then I can run queries and discover stuff I didn't know.
That's how I learned music theory, how scales and chords work, how to identify the key of a melody... You can't do that as easily and concisely in any other language.
One day, LLM developers will finally open a book about AI and realize that this is what they've been missing all along.
