AR will definitely be the way forward for all computing. This brief awkward period of 50ish years using analog inputs and physical screens which we are currently living through will be seen as a blip in the history of human-computer interaction hundreds of years from now. However the only use case for this iteration of the technology is for developers to begin working on new interaction paradigms and app ideas for AR in general. We're still years away from true consumer tech but I can admit as someone very familiar with VR/AR hardware that the Magic Leap One is a solid evolutionary step forward from what we've seen so far. I'm not impressed enough to buy one yet, but at least the company has shown they aren't total vaporware at this point and hopefully they can keep improving.

AR would replace the display, not all input mechanisms.
They tolerate glasses because they are a necessity for most wearers. But if you hang outside the LensCrafters store and ask people, nearly all would tell you they generally dislike wearing them[0].
[0] Yeah, I know, there are people who wear them for "fashion".
Hell, these days I find myself dreaming of AR contact lenses, so I could peruse some discreet computing in situations where I'm otherwise unoccupied, but the social context demands me not fiddling with a phone.
I don't think people ever enjoyed carrying things around(laptops, tablets, smartphones etc) but they do. They don't really like big loudspeakers or TVs or tv setup boxes either still they buy them.
I would replace both my laptop and my smartphone with a pair of glasses anytime(if it would be possible).
Smartphones and tablets didn't replace keyboards. They are good at somethings and laptops/desktops are good at others.
Turns out keyboards work great and are way less frustrating and more precise and the voice to text is only used in special use cases such as driving and for simple queries.
In terms of throwing ideas into text using as little effort as possible, Google has definitely nailed it with their transcription offering. Its incredibly accurate and free for consumers to use. Hopefully Sphinx and Mozilla's DeepSpeech will improve rapidly, otherwise this will remain Google's domain.
