I don't see the equivalence. Some people don't want to the bloat of the JVM, nor the bloat of Java libraries themselves. Some people prefer dynamic typing over static typing (and yes, I know Scala is type-inferred). Some people love Python's libraries and/or community.
It isn't clear to me why Scala is obviously better than Python as you imply.
