The author mostly argues that Python does not work the way they are used to. While I can understand that Python being different may pose a difficulty to someone who is used to JavaScript, C, C++, Java, and so on, there are many different languages that one can learn from. To me, a foundational language allows the learner to understand how computers work, and how calculations can be performed. In this light, SICP has proved that LISP can be a foundational language. I strongly suspect the author's notion of "foundational" is very different than mine, and that they see programming as something very different than I do. Without knowing how the author sees it, I miss the point of the article.
