Thank you for your comment @eturnerx
However, being computer code, producing convincing enough deepfakes is within reach of almost anybody.
That's the frightening true.
One solution is to have people digitally sign their communications so the sources can be challenged - but this also creates an environment of plausible deniability. A figurehead can say something controversial, not sign it, then disavow the statement if called out.
That's interesting conception. And sometimes video materials are not intended fur public opinion, but journalists sometimes manage to get them, not necessarily in a legal way. Such materials would definitely not have such digital sign.
Another would be to trust the sources that vet info and pass it onto us. However, trust in the mainstream media is extremely low.
That's true, especially when nowadays most mainstream media are targeted on certain political opinion. There are plenty "trusted" TV stations in Poland which regularly manipulate facts.
