Julia wasn’t really built specifically to be differentiable, it was just built in a way that you have access to the IR, which is what zygote does. Enzyme AD is the most exciting to me because any LLVM language can be differentiable

Ah I see, thank you for clarifying. And thank you for bringing Enzyme to my attention - I've never seen it before!

Enzyme.jl works quite well (but the possibility of using it across languages is appealing).
