This also means… we aren’t necessarily stuck forever with HTML, CSS, and JavaScript. We could make a new scripting language. We could make a new markup language - or, better, explore different paradigms that might be more suitable. Maybe there’s a better way than having a DOM in the first place. We’ll never have that discussion though if people are forever convinced of JavaScript being the pinnacle.
I say this as a person who is more willing to question whether ridiculous levels of abstractions means the underlying technology perhaps needs changes.
