Several of your examples are hard real-time systems. Garbage collectors, schedulers, etc. are a no-go in such environments, so you won't see much Python or JavaScript there, but that doesn't discount the value of those languages. Note that Ada, a high level language, is used in similar systems, and that Lisp has been used in NASA satellites. High-level languages like Erlang are used in telecom systems and other critical network applications. The fact is, languages created in the early history of computer programming have had the opportunity to be used in high profile projects like the ones you brought up. In time, you will undoubtedly see Python and others used in such contexts.
