The current icons really aren't that good. Looking at apple specifically: The facetime and messages icons are almost completely indistinguishable. Get angry and say I'm blind, but so is a lot of the userbase - like legitimately, legally blind people.

The camera icon on iOS is just a fucking camera lens with a grey background. No context.

The calculator one is actually pretty good.

The photos one is also bullshit lol.

Sure, but it's not clear they're unrelated. Maybe interesting is necessary (but not sufficient) for usability?

Also, the newer icons don't really indicate a word processing application. If anything, they're look like they might be for a drawing program. So regardless of interesting/abstract/whatever, it seems like a poor icon choice.
