I am not sure why you are downvoted.
Google has been doing electronic with ML for some time now : https://ai.googleblog.com/2021/02/machine-learning-for-compu...
Python and Tensorflow work just fine for that task, the speed comes from LLVM and dedicated hardware such as TPU. The language in which the high level ML network/algorithm is specified doesn't matter much.
It is always good to have several paths explored, but I'm skeptical on the Julia hype since its beginning.
