There is a TikTok trend running right now built on the premise that 2026 is the new 2016. Creators are pulling out decade-old sounds, filters, and dances and repackaging them with minimal modification. The comment sections are full of people who were teenagers in 2016 responding as though they have been shown something precious that they had forgotten existed. Ten years, apparently, is the threshold at which recent pop culture tips into nostalgia.
