WASM is still pretty niche, as is the desire to write a UI in something other than TypeScript/JavaScript

the "it doesn't have a UI library, and thus you are forced to write JS" criticism in particular feels odd to me. Given the reference to HTMX, I assume this person isn't building desktop apps, and in the web app world, TS/JS is by far the industry standard for the front-end

Pretty odd article.

WASM is not so supported, but it's not like a major technology right now.

If you need complex UIs, separate backend and frontend and write the latter in something well supported (like, i dunno... JS)

"The days of crappy NPM packages are over" said no one ever, and no one will ever say.

TS is never going to catch up with Go performances, and the lack of IPC and true concurrency actually is very bad for backend services that need to handle stuff.

I think the OP wants to use Go for stuff that isn't supposed to do with.
