The author of this notebook does not appear to agree with you. They describe Python in the beginning as "beautifully designed". This is not idiomatic Python code. It's code designed to demonstrate Python performance optimizations, through use of relatively obscure Python functionality which exposes details of the internals in situations where you need that. "its implementation, ecosystem and tooling are fundamentally at odds with correctness and productivity" You'll need a lot more than just this notebook to argue for that position.
