Python-the-language is fine, but any time I see people explain why they chose Python for a project it usually boils down to Python having an extremely large ecosystem of libraries to choose from. This means that any new-and-better Python would need to be take the Scala/Kotlin route by running on the same VM in order to take advantage of the existing ecosystem, but my understanding is that (unlike the JVM) the Python VM has no published API and therefore doesn't present a stable compilation target for any language other than Python.

This leaves Python in a space similar to JavaScript, where there isn't a really solid way to build a successor.
