Cameras in the future are not immune to what we may see on upcoming smartphones. For example, Sony revealed an image processing sensor with compute capabilities built-in. It's able to not only send photon measurements but send metadata on what's being captured in the image. https://techcrunch.com/2020/05/14/sony-shows-off-first-combi...
Remember when scanners would allow you to scan banknotes, even those with a Eurion code?
I suspect we'll be seeing more of this kind of thing in digital stand-alone cameras. GPS-enabled? You just lost the ability to photograph demonstrations. Trademarked logos i the background? Maybe the shutter won't click.
Scanners with banknotes remind me of my kid's LeapFrog book. It's basically a book and a pen which can read whatever you tap against. It has an optical sensor at the tip of the pen and the print just has a bunch of microscopic dots barely visible to the naked eye. https://en.wikipedia.org/wiki/LeapFrog_Tag
