We're rhythmic creatures. There's a reason we latch on to each other's tastes and habits. Emulation begets automation.
But there's always someone who comes along and challenges our beliefs, unlocking a Pandora's box of attitudes and topics we never even considered. All of a sudden, everything we deemed to be true goes into question.
The echo chamber calls for cogs of sameness and lookalikes. Once we lose the urge to conform, we are free to rejoice in eccentric delight.
