It's easy to miss, but the second bullet point about "coding in a low-level language directly" links to another of the author's articles entitled Cython, Rust, and more: choosing a language for Python extensions [1] which discusses the pros and cons of using Cython. I've done a pretty extensive amount of development in Cython. I agree, it's very nice to be able to incrementally type Python code but I've found that using the language to its full potential requires a good understanding of C programming, especially for debugging.
