The problem is misinformation, but it's always been misinformation. It's also a lack of trust in experts, because the rich and powerful have always employed some experts to represent their positions or skew the truth.

There's nothing new about misinformation.

What is new is how much it's being monetized today by networks of like-minded scum.

For example, if I wanted to sell dubious health products, it would probably be a good idea to set up Facebook groups that deals in nonsense memes so I can find my target audience.

The truth is, more of these "new info sources" are garbage than not because garbage is incentivized.

There's always been a sizable percentage of the population that simple doesn't know how to discriminate or question their sources critically. They were just as vulnerable to misinformation 30 and 40 years ago, but it was not as abundant as it is today.

Some flies will always find the shit.
