Take the team to read this one, especially the later section describing the Anti-Mac interface. It's incredibly prescient and basically describes the direction of modern desktop GUI + cloud + voice controlled assistants.
The article might be a bit aggressive on suggesting that language _replace_ icons, rather than augment them - but it seems just as likely that we're still in the middle of the transition and assistants being built from the ground up without icon-based UIs is exactly what the article is predicting.
Yeah, I scoffed at first reading it but by the end I was impressed. Definitely agree with the point that metaphors are less relevant in a time where many people know how to use computers. A virtual assistant with the power of a command line could be very useful (though you'd probably want to double check their work before executing it.)
