Black Mirror S01E03. Even with bullet-proof privacy, not a future I would want to live in...

What I saw in that episode was people being assholes to each other, the fact that they also happened to have a tool to prove things wasn't really the major factor. Especially the final point was a bit off to me, sure, it happens that we would be happier not knowing specific things, but being unsure about things can be pretty terrible as well and just as well destroy life.

We don't expect people to show us their diaries, we don't expect people to retell their awkward memories. We even generally try to gauge the situation before retelling a story about a friend (maybe their embarrassing blackout last weekend is not what we talk about with their boss). This is all in the social rules and conventions, and doesn't have to do with limitations in our ability to do so.

We already have the technology to record all digital communication. Seems like most people can handle this just fine.

Much like there is a XKCD for everything, there'll be a Black Mirror episode, too :)

Microsoft developed such a camera years ago (sensecam) . Ahead of its time, or possibly the hardware at the time didn't make it feasible.

Edit: it was called the sensecam https://en.m.wikipedia.org/wiki/Microsoft_SenseCam

I thought about that too, but ultimately decided it wouldn't be ethical. And probably illegal in many situations.

I've been to a few events (including pro privacy events). My understanding is that all you need (in the US) is to make them aware with a sign that says by entering this room, yada yada yada.

A wearable doesn't record only in your room, though; it goes everywhere you do.

but if it is only on device, (the video) then it is easily possible to get the device damaged, lost, broken, robbed in order to stop that retrospective analysis by a bad actor.

What if the data was synced between a small circle of your devices using end to end encryption and each device itself had full disk encryption with a strong security model to back it?

Prevents against most common data loss scenarios while protecting the information from bad actors.

My goal is not "preventing bad things", but rather "remembering interesting things".

Or a good actor. Let's not pretend it's only good actors that want privacy, and bad actors that want access.

i meant robbed or damaged by a bad actor, Analysis I meant for user's own use by user.
