I'm thinking lately the myth of the "browser" and "web" as coherent data spaces is something even Sir Tim gave up on, right? If the centre cannot hold constellations of specialised clients (which are already "apps" in a sense) look like enduring in the near future at the expense of interoperability and standards. The "best browser" will be the one that strikes the most deals with the parts of the network people want to connect to. It's just like the best "game console".
That seems really bleak for the Internet qua people's network.
No doubt http/s and the worlds of port 80/443 will endure eternal, but the "Universal" search and information space the pioneers and then proto-Google aspired to now seems so remote that the idea of a "browser" is itself a little ridiculous to beards like me. I think today the "browser" has become a clique of PKI suites and CAs, at the behest of banking and retail, backed by broken but well meaning regulation, and unwittingly creating this monster we still call "The Browser". anyway, peace.

So often arguments on this axis come down to how much convenience are you going to give up for the trust relation you desire. We get stuck if we mistake convenience for necessity thereby bringing absolutes into a continuous trade-off problem.
