I think the skepticism of new shiny things is healthy. Of the set of things that exist, most things are worse than the things one already uses/prefers. Most new things solve a specific problem that may not overlap with the problems one is trying to solve. With software development, a huge part of the puzzle is tooling (as the article points out), so even if typescript is obviously superior as a language, the tooling needs to catch up before it's a reasonable/useful alternative. In this case, the tooling quality, enabled by the static typing, shot typescript way past the thing it was replacing.
