Back when I lived in Austin, Texas, Alex Jones was just our funny cable access lunatic. He was like a funny wrestling match interview during a UFO convention. Then we built the modern internet. Sorry.
Maybe it's not done yet. The Arab Spring demonstrated that Twitter was a threat. The powers that be have effectively destroyed Twitter as an organizing tool. Now we have Mastodon.
It might take more than a few decades for humans to fully adapt to the internet hazards we were warned about in the 1990s and forgot by the 2020s.
