Learning different grammars/syntaxes aren't the hard part imho. The hard part is learning new programming paradigms and how to write good code in X language given the features under the hood. What makes a good Python programme makes a terrible/impossible C or Rust programme. It might not be hard to write Scala code like you might Java and have it run, but you're doing things distinctly wrong. That's the sort of language-y stuff that's hard to teach in Y minutes imho.
