The bad news: This can and obviously will be abused - be it by the secret services or hackers. The good news, I suppose: As fast and scarily as the tech to fake things is evolving, so is presumably the tech that detects fakes.
In general, you need to have examples of a type of fake to detect it.

> rapid tech advancements the past 50 years and we're still here This is a tautology. At some point the music stops and you aren't here to make the argument that we are still here.
not entirely tautological. the probability that something bad happens tomorrow if we do X today for the first time is very different than the probability that something bad happens tomorrow if we do X today GIVEN weve been doing X every day for 50 years. It is still insufficient to say nothing bad will happen, of course
Something I've wondered lately is what will life be like in a post-truth society? we already see examples of this now where a large number of people get their news from fake memes on facebook. There are huge swathes of people who live in their own make-believe world, like those believing wholeheartedly that the 2020 election was stolen. What will life be like when you can't trust any video or interview you see becaus…
I think we'll solve it the same way we solved similar transitions when text and image faking became easy: provenance. For many years now, most have understood that you can't take text and images as truth because they can easily be simulated or modified. In other words, the media itself is not self-verifying. Instead, we rely on knowing where a piece of media came from, and we associate truth value with those institut…

So there are information theoretic ways to certify that media is genuine, if you assume trust at least somewhere in the process. Basically just cryptographic signing. For instance, a camera sensor could be designed such that every image that is captured on the sensor gets signed by the sensor at the hardware level, with a certificate that is embedded by the manufacturer. Then any video released could be verified agai…
A hardware-based private key like this will inevitably be leaked.

The concerns raised in the first paragraph however... the next few decades are going to be a wild ride. Hopefully humanity eventually reaches an AI-supported utopic state where people can wrap themselves in their own realities, without it meaningfuly affecting anyone else. Perception of reality is already highly subjective, most of the fundamental issues are due to resource scarcity/inequality. Most other issues evaporate once that's solved.

I don't know. How would you "prove" it? Google it, and look for what other people that agree with you think?
Well... https://www.washingtonpost.com/world/2022/05/01/ghost-of-kyi... admitted by Ukrainians themselves...
"It's confirmed!", "They admitted it!", and other unprovable internet turns of phrase in comments sections are really just "I believe it because somebody I trust said so" and that only has weight as long as trust has weight.
What's the difference in NeRF from a classical photogrammetry pointcloud workflow? It seems like the representation and outputs are identical. Why would you prefer NeRF to photogrammetry? Or vice versa?
They also are proving to be faster, more accurate, etc
The input data is the same. Nerfs have the chance of requiring less input data.

Thats not the argument. The one you are making is the same one people make when they conflate weather and climate.

The concerns in your second paragraph can be mostly mititgated using a combination of trusted timestamping, PKI, cryptographically chained logs and trusted hardware. Recordings from normal hardware will increasingly approach complete untrustworthiness as time goes on.

I think being in the real world and meeting real people is the only way to create a real, functional society. Allowing people to drift away into their own AI supported worlds would eventually make cooperation very difficult. I think it would just accelerate the tendency we've seen with social media, creating ever more extreme positions and ideologies.
