Although I agree to the gist of it in terms of ‘Programming’; I may not agree in terms of ‘Programming Languages’.
IMHO, mastering a programming language to write clear, concise & idiomatic code takes time (sometimes more, sometimes less). I think of programming languages as tools; none is better than the other. It’s a matter of using the right tool for the right job.
Learning a tool takes time and dedication; often having experience with one tool may shorten the time required to learn another.
