As much I enjoyed Black Mirror I thought it's Season 1, "The Entire History of You" entertaining but was poorly conceived. It showed catching your partner cheating as a "would rather not know" thing and it ignored any possible positives. The episode wasn't really about the tech, it was about a failing relationship, a cheating partner, and an untrusting obsessive person.
In any case, in that world, which didn't have AI to review and catalog what you saw but only playback of recorded sight, positives they could have mentioned
* an end to almost all date rape - since it would be recorded - leaving only the ambiguous cases
* a likely decrease in various crimes - since they'd all be recorded
* harder for execs/government to make backroom deals - since they're be recordings of them
* might end gaslighting in personal relationships
* eyewitness reports/testimony would be way more reliable
* medical symptom checking - when did some symptom start would be recorded
* better performance review - like a pilot reviewing a training landing or an athlete reviewing their own performance.
* proof of abuse by customers or by staff.
* checking your actual time spent vs you're perceived time spent - I studied for 4 hours, checking though you studied for 45 minutes and kept getting distracted with non-study
* less lost items - check where you left your keys, etc....
* more accountable police - everyone is recording them
* no more need to take photos for memos, since you know everything you looked at is recorded
* all car accidents recorded - easier to determine blame
Of course adding AI to all of that would add orders of magnitude more usefulness.
I'm not saying there are no downsides. As one example, every bowl movement, shower, self pleasure, sex, cold, vomit, misspoke word, awkward situation, etc would be also recoreded.
