NO. Far from it. I can't work on a codebase with a colleague, me writing/reading the code in Scala, he/she writing/reading the same code in Java or Kotlin. I can't code a project in Clojure, then hand it over to a team of programmers that see it and work on it as Java code. JVM languages are too different from one another (and the "common language" underneath, whatever is it called, it's waay too low level to qualify, practically no one writes/reads it). Different syntaxes would mean need to share a different semantic common to all to have seamless translation. (And yeah, apart from some academic experiments I think we're far from abstract syntax independent semantics in any production used programming language. To actually be able to treat the multiple JVM languages as syntaxes of the same language with a "seamless" experience you'd need code analysis tools of almost-superhuman intelligence. By that point we'd be out of job anyway ;)
