> "Oh no that's sci-fi and decades away", I really don't think so. I think neuralink, and competitors too, will next move on to reading the visual cortex. They already have plans to push data to the visual cortex, to enable the blind to "see", reading in healthy people seems quite doable.

I think 2030 is too early for that, medical tech is slower than most people expect. What may happen by then is (more) retinal implants connected to external cameras, as the early tests of that kind of thing are now well into the past and early models were actually authorised: https://en.wikipedia.org/wiki/Argus_retinal_prosthesis

The non-medical surveillance risk is higher. The smallest camera (as of 6 years ago) was already small enough to be easily missed amongst makeup sparkles if you were so inclined: https://originalpricing.com/ov6948-medical-camera-sensor/

Low resolution? Sure. Expensive, too. But I can easily see this being embedded in someone's nail lacquer, or eyelashes.

There have been hidden cameras of various kinds for a lot longer than that, hidden in buttons etc.

Between this and how easy it is to use AI to fake a picture of anyone you choose, anywhere you choose, doing anything you choose… I have absolutely no idea what will happen to consensus reality and shared social norms next year, let alone by 2030.
