The real entertainment is in the comment section.
It’s a rapid delivery system of witty content with the best and funniest comments pushed to the top by voters.
Comments take five seconds to consume while the video plays in the background.
The background noise fills the noisy mind, while the dopamine flows as we see each new bit of info and get our reward.
Thus the comment section of passive entertainment (video and audio content, primarily) provides us with the illusion that we’re watching and learning, but in reality, we’re getting our dopamine hits and loving every bit of it.
