Google is hugely invested into Python, especially the data engineering branch. TensorFlow, Jax, etc. Though they will probably get replaced by Dex lang, they even dropped Swift 4 Tensorflow to focus on Dex [1]. The language looks very Pythonic compared to Julia which is a 180-degree turn in terms of language design.
Take a look at the code examples, looks like Python & Numpy + Haskell had a baby. And yes, it is developed by the creators of PyTorch (the irony) and some of the guys from Tensorflow, Jax and S4TF at Google Research & DeepMind. Read their paper here, it's pretty interesting. [1] It may never become an actual production language but it is many times more interesting than both S4TF and Julia.
