When I look at the popular ideas on all sides of the political spectrum, the trend seems to have been toward ideas that are not only more one dimensional and extreme but more irrational and incoherent. I regularly come across online comments that are borderline word salad, a blathering incoherent mess of the sort that would in the past have immediately led to questions about schizophrenia.
It doesn’t seem to be a specific idea so much as a decline in the lucidity and coherence of cognition itself. The ideas are inane, but I can’t imagine such inane ideas taking hold to such an extent in earlier eras.
I have only two hypotheses that seem like they make sense: gamified social media and CO2 concentration impacting metabolism. I lean strongly toward the former because around 2010 is when algorithmic timelines started to be introduced and it was right around then that I remember a tangible sense of sharp decline. I had to include the latter for completeness, but I hope not as the latter would be far scarier.
Social media companies are the tobacco companies and opiate dealers of the information age. The more I see of them the more I am convinced they are an objective evil and create net negative value. The algorithmic weighting of content for engagement seems to be the real problem, but it’s at the heart of their business model now.
