I think this remark from another thread is relevant:

> [@What steps should the Julia community take to bring Julia to the next level of popularity?](https://discourse.julialang.org/t/what-steps-should-the-julia-community-take-to-bring-julia-to-the-next-level-of-popularity/101389/313):

> Julia is **almost surely not** going to displace Python for ML because Python for ML is actually C++ for ML. As such, replacing the Python ML frameworks requires Julia to be dramatically better than C++, not Python.

If most the execution time takes place in kernels written in a fast language, then Julia is likely not anywhere near 100x faster. In fact, if those kernels happen to be more optimized, then the Julia version might be slower.
