Mastering a more powerful tool prepares me for more appealing roles solving harder problems. Time spent on a weak tool is just wasted; it'll never get better and neither will I. Java has become reasonable though I'd always reach first for Scala or Kotlin (maybe Clojure?) I'd like to work with Rust but it seems hard for an employer to cost-justify the dev work to avoid paying for G1.
