From a engineer mind share pov they are. Users don't use them. Engineers do not build them.

They are stillborn and i don't see a way out.

I think the expectation that tech wins & is everywhere in 5 years is murdering useful progress. It's not the climate we are in any more. Success is slow boiling, especially for web standards.

The lack of empathy for how long change takes keeps letting doom & gloomers send good things to the graveyard.

Engineers build them for big corps and ecommerce sites.

The respective users, specially the corporate ones, have no alternative other than using them.
