Classic WIMP paradigm arguably lost dominance already in late 00s/early 10s. Windows 8, Office 2007, Gnome 3, iPhone, web applications, all were exploring new stuff and breaking conventions. And then you also have the skeuomorphism fad, and lots of other little things.
It is also noteworthy that even at the height of WIMP era lot of user interaction was driven by keyboard shortcuts, arguably even more than these days. In many ways WIMP was training wheels instead of the primary interaction model.
