The internet turned 55 in 2024 — and for most of that time, humans have been adapting to it more than the other way around. In the span of a single generation, a global network built by researchers to share data has restructured the most intimate parts of daily life: how people wake up, how they grieve, how they argue, how they shop, how they find community, and how they understand themselves.

The changes are easy to underestimate because they happened gradually, invisibly, one browser tab at a time. No single moment announced that memory would work differently now, or that loneliness would take a new shape, or that attention spans would become a contested resource. These shifts arrived through habit — through a billion small decisions to Google $GOOGL -3.86% something instead of ask someone, to text instead of call, to share a photo rather than describe a moment in words.

Some of the changes are clearly beneficial. People have access to knowledge and community that would have been unthinkable before. Patients with rare diseases find each other. Diaspora communities maintain language and culture across borders. Small businesses reach global customers with almost no infrastructure. Self-taught skills that once required formal schooling are now available on demand.
