We are getting new form factors, they're just so radical you don't recognize them: laptop->tablet/phone, phone->watch, desktop->VR headset, home assistant. None of them are perfect substitutes yet, which is why the old form factors persist, but look at how many people are doing on their phones today what used to require a laptop or desktop. It's not hard to imagine a watch plus earbuds replacing the phone for most (but not all) users, and home assistant replacing a desktop for some (but not most).
