Civic life requires unchosen, recurring, place-bound encounters

The recipe isn't complicated: necessity, recurrence, social mixing, and a defined place. These four conditions generate return loops -- the same people, the same location, over and over -- that build familiarity and shared stakes. Historic town squares had all four because commerce was daily and local.

Almost nothing in modern American life meets this bar. Transit hubs have necessity and recurrence but are for passing through. Playgrounds and dog parks are chosen destinations. School pickup and drop-off is one of the last genuinely local rituals left -- parents temporarily stranded together, repeatedly, over weeks and months. It has the ingredients. But even here, most parents wait in their cars, and those who do get out find nowhere to linger once the kids arrive.

The internet gives everyone a stage and nobody a town. No algorithm changes that, because algorithms connect willing participants -- they don't generate the unchosen friction that civic life actually runs on.
