Nonsense. Transpilers have been misused at times in the javascript community, but overall they have played a *massive* role in modernizing javascript and enabling us to write much sounder, more robust, and bug-free code that runs everywhere, including on older devices and runtimes. Society as a whole has benefited immensely from babel and other transpilers.
As time goes on, transpilers may ultimately become slightly less valuable, however for the past decade they have allowed us to grow and improve our javascript without sacrificing portability.
