I've been thinking about human communication and how much it changed over time.
It crazy to think that before the printing press, the most efficient form of communication was word-of-mouth. Word-of-mouth only conveys a very vague, unreliable description of reality. Communication was unreliable. People knew they could not fully trust what was communicated to them; not only because the original material may not be reliable, but people knew the message could have been distorted as it propagated through the population 'Chinese Whispers' effect.
Then with the printing press, communication became a lot more reliable; people did not have to worry about 'Chinese Whispers' anymore, they knew that what was printed likely came directly from the source...
Then photography came along. People trusted photos completely for a time. It was high-resolution evidence; wars could be started over it. Then as photo-editing tech became more powerful, people started to doubt photography but then video came along and created a new medium for reliable communication which was hard to fake. CGI never got quite to the level that it could not be distinguished from reality.
Now AI is making video unreliable... We will have no way to verify the authenticity of detailed visual communication. So we will lose trust in it.
Maybe something like blockchain will help us to get back to a certain level of communication reliability in terms of source authentication... but the resolution has been lost permanently. We will never again be sure if something really happened with quite the same level of certainty. We go back to a kind of 'printing press' level of reliability.
The resolution of the communication (the amount of detail) doesn't add to its reliability anymore. We shouldn't underestimate how much of a role video has played in creating the highly centralized over-trusting society which we have today.
Would people give governments so much power if they couldn't even agree with certainty about who said what and even who won the election?
