If you're gunna post a blog, at least choose one that writes well.
Our Qwerty keyboards are ubiquitous. You may think there are no problems left with that design, until you are hit with carpel tunnel pains.
Before that, you would not even be aware of the problems and their myriad solutions: better layouts, better hardware designs (like split body or 3d sculpted), or even conceptually unique input devices.
Saying that there’s nothing left to solve signals your position among the conceptually impoverished. It is fine to not know, but it is not wise to proclaim that no one else does or will ever know.
Back to browsers. How could a solution ever arrive? Perhaps someone assumes there is a better way and try to build new things? Should we have instead stopped at letter writing or fax for the solved problem of communication?
I am just glad that there are people who are willing to take on risk to pursue a solution, for problems we are too stupid to care about.
Calling people stupid is not a useful response.
