People create new languages (for the most part) when it helps them substantially improve their capability to solve the problems they care about (I.e. “delivering value”). If you don’t feel the pain of those problems enough to understand why the improvements matter, then you can happily ignore the new language hype. I can’t comment about the JS ecosystem, but every new language (~half dozen) I’ve learned has given me new perspectives on solving problems, and sometimes the language itself serves as a better tool I reach for frequently. This may be somewhat biased by the fact that the problems I’m most interested in are typically algorithmic/mathematical in nature, and YMMV for different classes of problems.
