I’ve heard it said and I won’t argue your personal experience.

However, I don’t see it that way at all. I find claude much more capable of writing large chunks of python or react/js frontend code than writing F#, a very statically type-checked language. It’s fine, but a lot more hand-holding is needed, a lot more tar pits visited.

If anything, it seems a popularity contest of which language features the most in training data. If AI assistance is the goal, everyone should write Python and Javascript.
