> editing it on a computer, and then "printing" it back out to a DNA molecule

That's kind of what Novavax claims, search for the interview with David Rubinstein on WEF. NVAX wants to print short fragments of virus's proteins, so the resulting vaccines supposed to be safer than those made by working with live viruses.

Accessibility utils like screen readers do OCR and read aloud the content for blind people.

All correct. It's just important to remember who's the attacker:

  Alice -- ISP1 -- 1000 hops -- ISP2 -- Bob
Alice and Bob's identities are protected from each other, but not from the govt because ISPs collect metadata.

Yes, overlay network's configuration will be somewhat different, but physically it will be the same. It's like you're rearranging apple bits in a pie to save them; the pie will be sliced and eaten anyways.

I doubt the number of nodes is important when you can split a large group of them into a few subgroups and analyze them or alter how they interact with each other, then repeat subdivision; because again, them overlay networks are like smaller sandboxes inside the big one.

> I wonder why there are so few people

Maybe because people understand that it's security model is flawed: the peers in the mesh treat all the other peers as not trusted, that's okay; but the network design doesn't seem to take into account potential hostility of the physical medium itself.

Say, your ISP can tarpit packets or shape traffic, or shut down the power or cell tower in your block temporarily, and then measure how the mesh congestion changed. At the same time the mesh relies on building hop chains with TTL of 10 minutes iirc, which I think makes a peer a sitting duck. It is (was) all documented/leaked.

Huh, your imaginary city reminisces one in The Murderer by Ray Bradbury.

> I don't fully grasp what privacy is

> people like me find it hard to quantify what that thing is

Privacy is [REDACTED]. Intelligence is not privacy.

Recently I cleaned some olde books I don't need anymore and there were a bunch of them on info security, so I skimmed them good bye, and they all stated the same vague definitions like no one knows what privacy is, there's no agreement, etc.

Actually there're definitions of privacy and intel, they are just sad and unethical, hush shush.

It seems like the context is built with a simple bag of words model. One day I searched "how to make a mousetrap", the following day I got a recommended video about statistics, where the author explains something on a mouse population, and says "mouse" many many times.

It's not that easy. Take into consideration spreading of sensors like light/water/gas/sewerage meters, which report measurements to a central SCADA. I touched that around a decade ago, I had to build link with the meters with AT commands through GSM with modbus protocol on top of that.

These days it's a grown-ass market with competition and much more advanced toys involved. You turn on water, they know timings and how much you used. You use more electricity, they call you to suggest a different plan. You used drugs and flushed, they find metabolites in sewerage sensors (I heard that on news, dunno maybe bs).

So I think it's basically about bills; cameras in toilets are different market.
