I do so much in my browser these days, things I had to have 15 applications for back in the ie days.
I see the news in the front page of HN: Edge, Firefox, Ladybird. The problems with privacy, funding, etc. will remain as long as one refuses to do an "AT&T" on the Web, that is delegate the non-essential browser functions (text, image display) to other applications (e.g. VLC for video, audio).
With a strong emphasis on banning remote code execution (JS), the father of all evils.
It may be convenient to call a coworker from Teams in your browser, but it is not a sane way to do it because we end up to where we are now: browser oligopoly. Convenience can be a trap; scammers and phishing use it all the time by including "direct" links. People are told again and again to know better and use their bookmarks instead.
If your goal is to get rid of all the fancy stuff, then yeah - gopher still exists, all UX can be thrown out the window, it all exists today. But I don't think that'll go anywhere, except in extreme niches.
