Is it a good time for a PyTorch developer to move to Julia? If so, Flux? Knet?

Models on GPU in Julia will be slower than the same models on GPU in PyTorch, while models on CPU in Julia will be faster than models on CPU in PyTorch?

Also, can you elaborate on “some tracing and compiler stuff gets done”? I have some features pending improved performance of code compilation / tracing, so any news on that front are appreciated.

In the short term, GitHub - MikeInnes/Mjolnir.jl: A little less conversation, a little more abstraction

In the medium term, Add `AbstractInterpreter` to parameterize compilation pipeline by staticfloat · Pull Request #33955 · JuliaLang/julia · GitHub and future PRs building on it will allow faster and more composable Zygote, Cassette and other code transform packages built on typed IR
