Can we stop innovating on UI for existing problems?

The standard affordances for most well-known problems are long settled. Unless you're solving an entirely new class of problem, maybe you don't need to reinvent a large number of wheels, again. We're all tired of the triangular wheels coming out.

Which makes it funny that the request for UI innovation is prefixed with a quote that amounts to "but what if browsers were permanently frozen ca. 2012?". Mind, I can sympathize with some of the thoughts behind the request, even if I disagree - but you can't ask for a stop in new features & problem classes to be accompanied by continued UI innovation.

That is, as my art teacher used to say, "intellectual wankery in the disguise of creativity".
