Is it? We still need meatspace humans to vet what these AI agents produce. Languages like C++ / Rust etc still require huge cognitive overhead relative to Python & that will not change anytime soon.

Unless the entire global economy can run on agents with minimal human supervision someone still has to grapple with the essential complexity of getting a computer to do useful things. At least with Python that complexity is locked away within the CPython interpreter.

Also an aside, when has a language ever gotten traction based solely on its technical merits? Popularity is driven by ease-of-use, fashion, mindshare, timing etc.
