>How can this be fixed?
People stop trusting what they read on the internet.
All alternates are just attempting to improve the baseline trustworthiness of random information from the internet (and/or LLM that's baby-birding it back to you). Any increase in how much people blindly trust random stuff from the internet only serves to increase the blast radius when it is wrong.
My personal belief is that AI is eventually going to force the populous back to more face-to-face interactions. There will be a breaking point where people can’t take the “is this a human or a bot” guessing game any longer.
