Yeah, because he did so much for Python tooling at Google.

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.

All of the Tensorflow underlying libraries are implemented in C++ and nowadays usable from almost any language with native interop.

As for Dex,

Where is Python?

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.

Oh this looks nice.

But it’s also a google side project, so previous experience dictates that it’ll be dead somewhere between arrival and 5 years time.
