Well, Martin is more like a great PL designer and coding machine (most of the core scalac is his code) who also just happens to be a professor in his spare time (when he isn't working on Scala).
I did not meant it in a negative way, just to illustrate differences in language. Kotlin is an industrial language designed to interact with and enhance large java code-bases.
Even though the students and postdocs definitely contributed, it is still probably accurate to say most of Scala was created by Martin Odersky.
