That change resembles the speed at which Earth circles the Sun. We feel like we are standing still. But Earth is already running through space at about 30 km per second. That is more than 100,000 km per hour. We were already moving. Future mobility makes that fact audible inside everyday life. A car becomes another orbit laid on top of that rush. 2040 — Sensors wake first The moment the door opens, the sensors wake up first. Light scans the person.

The Classroom After Humans: Genes, Brain Energy, and the Physics of Attention No score appears—only the quiet data of recovery returning to the body. © Rainletters Map Field-style informational essay The Classroom After Humans The moment physics, genes, brain, and cosmos begin to meet inside one species.

Restructuring of Human Attention We have already entered another density We have already entered an environment of a different density. At some point, the same words began repeating across the world. Attention does not last long. We stop while reading. Thought no longer continues in long lines. Many people experience this change as if it were a personal failure. Lack of will. Lack of effort.
