Do you believe the general public is better at filtering out misinformation than they were 100 years ago? What about 500 years ago?
It takes time but people do seem to get better at filtering out mis-information. I believe (and we have some evidence) that we can speed this up by helping teach critical dissection of articles and content and build the skill set to weigh sources.
The problem will never go away entirely. It's an arms race between people who want to get closer to understanding reality, and the people selling a story to some end (profit, power, etc). Like all arms races, sometimes one side lags behind but they usually adapt and leap ahead.
We've never had yellow journalism powered by trillion dollar companies that are extremely good at manipulating your average Joe to keep consuming more based on their addiction algorithms.
Those were the conditions of the original yellow journalism, including people who would literally chase you down on the streets shouting headlines at you and trying to get you to buy a paper on your way to and from work. You had people in backrooms analyzing sales based on different newspaper features and writers - and figuring out what headlines would sell the most.
+ I ate two slices of proscuitto and blue cheese pizza for lunch
+ Software engineers get paid a higher average salary than babysitters
+ Yesterday was before today (and any other tautology)
+ My feet are cold
There are plenty of truth value functions we can evaluate for non-physical states including tautologies, personal opinions, statistical norms with broad support, historical events and so on. They may have different truth value functions (how we determine the truth of my opinions on how cold my feet are is different than how we determine the truth of what I ate for lunch) but they still have truth/non-truth outcomes.
Anytime you get into awkward philosophical quandries about the state of things, state the problem to a small child and see how they answer. This technique would of really saved Anselm a whole bunch of time and trouble.
Humans have a "truth default" in communication. We take almost everything we hear as fact by default. Bots will have no trouble at all making the majority of people think, see, and do whatever they want.
I'm not sanguine. Be honest, which would you bet on happening in the majority of cases?
I wonder sometimes if it's almost part of some fundamental psychology?
