Another word the Singularity needs: thread line n. /THRED line/ A queue for scarce GPU compute created by blocking new AI data center construction. The 20th century had bread lines. The 21st may have thread lines. When demand for intelligence grows faster than the infrastructure that produces it, compute gets rationed: longer queues, higher prices, smaller allocations, slower science, fewer experiments, less access. And unlike a natural shortage, a thread line can be entirely self-inflicted. Ban the power plants. Block the substations. Stop the data centers. Then act surprised when there isn’t enough compute to go around. The irony is that digital intelligence feels immaterial right up until you run out of the very physical infrastructure required to make it. Bread lines rationed calories. Thread lines ration intelligence.
