Realistically, it’s also a function of how many iterations it takes for an AI agent to correctly solve a problem with a given language. I’d imagine most AI agents would frequently have to redo J or F# code, as they are fairly uncommon languages with much smaller training set than JavaScript or Python.

I can say that for F# this has been mostly true up until quite recently. We use F# at work and were mostly unable to use agents like Claude Code up until the release of Opus 4.5, which seems to know F# quite well.

(I concur, Opus 4.5 is quite capable of writing F#.)
