> It will take years for large codebases to be upgraded to Scala 3

Which for production level code bases means never. I can't even imagine what we are going to do with our 7 year old Scala code base.

It's the Java 1.4/Java 6/Java 8 problem all over again. Big companies refuse to keep up with the base languages, and important parts of the ecosystem (e.g. Spark) fall behind the language.
