This presumes the existence of important "other activities", and relegates this content consumption as some lower-priority thing done between these activities. I know people who really don't have any important other activities: passively scrolling through video after video is their primary activity. For this [I'd guess growing] group, VR's ability to block out the unimportant real-world is the next obvious step.
3d video served by an AR sunglass display is plausible (but probably way overkill for the next decade), but feeling like you're in an entirely different environment while waiting in line at the post office is never going to be a thing people want.
The same was said of video vs. reading. “I’m never going to want a video experience, it doesn’t fit in between other activities as well as reading a page of something.”
There is a middle ground between "AR will never take off as an entertainment medium" and "AR will kill video/images/text."
I see a future where you blink twice to power up your ocular nerve implants for a few minutes of stim, then power 'em down when you get a popup that your buddy is nearby and ordering drinks.
Google Glass's spectacular failure had a chilling effect on the entire industry, but it failed due to (1) lack of killer apps, (2) poor aesthetics, and (3) consumer concern about privacy.
But ML has revolutionized image and video processing, Apple etc. could design a less hideous headset, and nobody cares about privacy anymore.
I think it would help to not make most of the promotional material about video recording, and not make a huge camera the most visible feature. I don't think it's a coincidence that the Quest lineup, including rumored Cambria and Apple renders, obscure the forward looking cameras.

The Snapchat glasses, as well as the Instagram/RayBan glasses don't seem to have suffered from having a prominent camera, which suggests there was a change in mass acceptance of cameras.
