@benroyce @NicelyManifest @JigmeDatse @redsad it's worse as propaganda is targeted and deliberate. A firehose of falsehood serves to undermine a communication channel by saturating it with noise.
But AI goes beyond this by its broadness. It pollutes all communication channels without discrimination ans without pilot and devalues any information or item of expression we can have access to. Leaving only those things that have been provably handmade with intrinsic value. Even historic artefacts like the photo in OP are not to be trusted anymore.
You're right that it means we can no longer trust anything we read or hear, but as a Frenchman brought up in Cartesian philosophy, I would argue that we should always doubt everything, that is the only healthy mindset.
