It is just a classical Dijkstra strawman - hiding a weak argument behind painting everybody else as idiots. In fact it is much easier to make dangerous undetected mistakes in C than it is in Python.
I downvoted you. First of all, your explanation of what "classical Dijkstra strawman" is lacks the substantiation. Second, your statement about C vs Python is a sort of strawman itself in the context of static vs dynamic typing. You should compare Python with things like Java, Rust or Haskell. (Or C with dynamic languages from similar era - LISP, Rexx, Forth etc.)
Presumably no one thinks "I love using [dynamically-typed language] because I can make mistakes easier", but on the other hand, isn't it the case that large codebases are written with low initial friction but high future maintenance?
A charitable interpretation would be he critizises e.g JavaScripts silent type coercion which can hide silly mistakes, compared to e.g Python which will generally throw an error in case of incompatible types.
