After reading these books, OP's article feels a little under-researched. Content aggregators like HN, Reddit, Pinterest, and Twitter are essentially using reality as a content generation algorithm. The content provided by reality is the variable reward component of the hook model shown in "Hooked".
It's not just that there's tons of information, it's that we're wired to seek novelty. This is also seen with pornography addiction, which is a more widespread phenomenon than most people realize, or admit.
From a product perspective, is it possible to take advantage of this wiring of the human brain to perform useful work? In other words, if we're wired to seek novelty, and we can create information products that are highly addictive, can we direct human attention to particular problems?
That's not to say that comment chains on Reddit don't provide value, but so many human hours of effort are spent glued to these novelty engines. It all seems inefficient, unpurposeful.
But then again, if the wheels of the economy keep turning, that's all that matters, right? Where are we headed?
