The Radio Drill That Taught a Crowd to Think Together
In the town hall by the sea, a storm drill starts and dozens of handheld radios crackle at once. Voices pile up until the coordinator tapes a map to the wall and taps three simple talking rules.
Last time, everyone tried to call everyone. With a small group it was messy, with a big group it turned into noise, and long updates got stepped on. Some text-reading AIs hit the same wall when every word tries to check every other word.
The new plan borrows a trick from an AI called BigBird. A few dispatchers can hear everyone, and anyone can reach them. Most people talk only to nearby zones on the map, and once in a while a zone makes a surprise check-in far away. Radio users are words, links are who can consult whom. Takeaway: hubs plus local talk plus a few long hops can carry meaning far with less chatter.
The drill runs. A river volunteer tells the zone lead, the lead passes it to a dispatcher, and the dispatcher sends a short summary to the shelter lead. The dispatchers keep collecting, squeezing, and rebroadcasting what matters, so distant spots stay in sync.
Someone asks, "What if we must compare every zone to every other zone right away?" The coordinator nods, that’s the weak spot. Without direct links everywhere, some comparisons have to travel through several rounds, so it can take longer.
Still, the room can handle a much larger crowd because most talk stays local and only a few voices carry the big picture. BigBird aims for the same win with long text or even DNA, where clues can sit far apart. The coordinator pulls down the map, and the radios sound calm instead of crowded.
