I watched those early google talks too and he’s right that doesn’t seem like what they were promising earlier.
I think OP confused including components using native HTML style tags would somehow also help solve the giant disparity in what you can accomplish with pure html/css and with JS added on top.
The stuff about JS being dependency and framework heavy seem thrown in but is a bit of a different problem and often comes with the territory with any complex JS.
If Web components weren't ever really going to promise a new JS free future (other than being a clean way to maintain complex layouts and import isolated/reusable chunks of UI) then those ancillary arguments about the JS ecosystem are a different and somewhat unrelated problem.
This is mostly about the others misguided idealism that doesnt sync with the IRL demands on frontend development for interactivity and complex state management vs the very limited offerings of pure HTML.
