A decade ago, a tribe of JS partisans took the web by the reins, forked HTML and JS syntax, and yeeted userland abstractions into the critical path because "a better user experience".

They could not have been more wrong.
JS-first web development has been a planetary-scale exercise in the rich making life harder for the less well-off.
