Kevin Kelly ruminates on YouTube's love of improbable events:

Superlatives were once rare — by definition — but now we see multiple videos of superlatives all day long, and they seem normal. Humans have always treasured drawings and photos of the weird extremes of humanity (early National Geographics), but there is an intimacy about watching these extremities on video on our phones while we wait at the dentist. They are now much realer, and they fill our heads.

His fear:

What happens if we spend all day exposed to the extremes of life, to a steady stream of the most improbable events, and try to run ordinary lives in a background hum of superlatives? What happens when the extraordinary becomes ordinary?
