Ah, I see you've not encountered any performance magicians, sleight of hand tricks, etc.

Receiving and trusting information is essential to being human. We don't have to prove everything to ourselves from sensory evidence and first principles because other people can credibly tell us things.

#5Anyone know how resistant this could be to cropping, scaling, or grading? Is this purely for verifying the raw or could this be something that social platforms could verify and tag on posts?

Eh, Language is a mechanical behavior involving interpretation of sound. Triggering sensorial experience is how other people credibly tell us things.
We have to verify via prior sensory experience (past experience) if the person speaking in the present is credible. How do we do that with limited sensory experience of their character? Personal ignorances and biases due to lack of experience?
We have to understand how to leverage the first principles of math to extend them, and teach those to others to propagate the knowledge.
Not really sure it’s possible to remove sensory experience from … well any understanding of the world.
Not sure what you wrote makes any sense.

#7I can't wait to take real pictures of a high-resolution display
(or even, interpose the bus connecting the image sensor to the rest of the camera)

The idea is that full edit history is preserved - not verbatim in the metadata, but as a tag that can be looked up in a database. More info here: https://c2pa.org/

Attesting documents is an old and important social technology.
Here in the UK, the police have a long tradition of using pocket notebooks to record their observations and activities. It is a professional duty to make a contemporaneous note of anything significant that happens during a shift - attending a crime scene, observing a suspect, taking a statement from a witness. Each notebook has a unique serial number, which is recorded by the officer's supervisor when it is issued to them. Each page of the notebook is numbered sequentially. Each entry in that notebook must be closed with a line, the time and date and the officer's signature.
When a police officer gives evidence in court, the defence will ask to see their pocket notebook as a matter of course. If the evidence they give isn't corroborated by their pocket notebook, a jury or magistrate is entitled to draw their own conclusions about the veracity of the testimony. If an entry is obliterated or a page has been torn out, if the entries are out-of-sequence or don't match with the dispatch logs from the day in question, that's obviously a cause for significant scepticism and may constitute an act of professional misconduct.
A notebook with numbered pages isn't a particularly clever technical innovation, but the practice surrounding it creates a great deal of value. It doesn't infallibly prove that an officer is telling the truth, but it creates a lot of hurdles and pitfalls for a dishonest officer. Likewise, in-camera signing of images doesn't prove that an image is an accurate reflection of reality, but it does make life more difficult for dishonest photojournalists or insurance assessors or forensic investigators. It gives few firm answers, but it does allow us to ask useful questions. If you're presenting an image as evidence, is it signed? Do the timestamp and geotag fit with your testimony regarding the circumstances in which the image was taken? If not, why?
