Ask a commuter what changed their music lately and the honest answer is often an algorithm: Discover Weekly, autoplay drifting into some stranger's song, a recommendation that lands sideways. Watch time dies from boredom, so platforms are built to mix familiar with novel, exploring on purpose. The other side's tightening loop describes the user, not the machinery whose literal job is surprise. Sure, someone can live in a five-genre room, but the algorithm didn't build it; it propped the door open. Blaming a feed for a closed mind is like blaming a library for an unread shelf.
