Sure, there are a lot of promises but I don't see the usefullness atm.
Like with KDE4 it was supposed to know in which language I am typing and anotate my downloads with the URLs I downloaded them from. Does it do those thing by now?(Years later)
People seem to want simple, predictable, fast and well animated UI (as in hiding common pauses with animations).
Apple is king there. I personally think that "just" trying to be FOSS iOS wouldn't such a bad goal. QML on Linux with Wayland allows fast and well animated.
I don't see how this UI doesn't look messy and complicated to your average Joe. Getting those "activity" suggestions right will be long and painfull process and may be abandoned halfway.
But I guess KDE is not for starting with something simple and going from there, they need build for a future that may never come.
PS. Before people think that only hate change etc. I love Nokias Swipe-UI. It is super simple, fast, well animated and IMO superior to everything we have atm (minus the apps of course).
We need Nokia to release the code or start an FOSS implementation.
I guess I have code to write now. Bye.
