Someone recently highlighted the shift from social networks to social media in a way I'd never thought about:
>> The shift from social networks to social media was subtle, and insidious. Social networks, systems where you talk to your friends, are okay (probably). Social media, where you consume content selected by an algorithm, is not. (immibis https://news.ycombinator.com/item?id=45403867)
Specifically, in the same way that insufficient supply of mortgage securities (there's a finite number of mortgages) led to synthetic CDOs [0] in order to artificially boost supply of something there was a market for.
Social media and 24/7 news (read: shoving content from strangers into your eyeballs) are the synthetic CDOs of content, with about the same underlying utility.
There is in fact a finite amount of individually useful content per unit of time.
