I think the internet in and of itself was fine, misinformation used to be shouted down.
Social media has allowed curation and bubbles to the point you are no longer confronted with inconvenient facts that you don't like.
Like Bo Burnham said in his song, something about 9/11 really messed up both the internet and our psyches. We all wanted to act like it hadn't happened, and that's how we end up with Spewers like Alex Jones. Oh, and the return of measles and polio.
I feel like a lot of the 9/11 conspiracies were people who DIDN'T WANT what actually happened to be possible, so they invented the reality they wanted, and submitted it as their "truth". They even called themselves Truthers.
As to the Covid boosters, my next Dr. appointment isn't until December. Each one beats me up a little more. I'm on Dose 4.
I have a medical center nearly across the street from me, and I had a really nice doctor there, but my insurance decided to make me go 17 miles away.
For a while I was going to a doctor six miles away, but he started getting... creepy and suggestive.
