This is why we need decentralized cryptography based digital ledgers to keep track of everything. A single human mind will soon be 100% incapable of proving that second hand information is factually accurate.
I'm not against the technology demonstrated in the video. Such technology is inevitable, and when we can finally all agree that advertising and financial/political/economic based use cases are all short sited half-measures, made to compensate for (or abuse) a severe drought of information pertinent to the 'quality of life' of those consuming the content, they could help dissolve fear based control systems.
If the language we speak (verbal/nonverbal/etc) can evolve to be incapable of devaluing the lives of everyone and everything, in favor of ensuring our own second by second preservation, there would be a cascade of corrections to the current system, universal harmony of all life being the inescapable eventuality... ideally.
Kind of like the movie "Arrival" except completely different because that was a movie made for people who communicate via the language of money and violence (not your fault, we all do, we were born into it).
