AI in Action
Beyond the buzzword: how much is the machine actually allowed to decide?
6 stops · 6 cities · 6 countries · 2012–2026
Six places where machine learning runs real city infrastructure — ordered by how much authority the system holds. It answers a question the word 'AI' hides: does the model answer a question, flag a document, retime one junction, or act on the whole city at once?
Read in order: every stop goes a step further than the last.

- 1 🏛️ Boti — WhatsApp City Assistant The machine answers. A chatbot inside WhatsApp that renews licences and books appointments — millions of conversations a month, and no decision of its own.
- 2 🏛️ „Aufenthalt Digital“ Goes AI The machine flags. An add-on to the national residence-permit service checks whether uploaded documents match what is required, and tells the applicant before an official sees it.
- 3 ⚡ AI-Driven Demand Response for Copenhagen's District Heating The machine shifts load. Predictive control moves heat demand across buildings — a 22% cut in morning peak load in the pilot, on a system whose owner still sets the limits.
- 4 🚲 Surtrac AI Traffic Signals The machine acts locally. Each junction optimises itself and negotiates with its neighbours — the decentralised design scales more easily than a central brain.
- 5 🏛️ Digital Dubai The machine runs the counter. An emirate-wide services platform bundling about 370 services, whose headline figures are paper saved and hours returned — activity, not outcome.
- 6 🚲 City Brain The machine acts city-wide. One platform gets every camera and GPS feed and retimes the lights. The gains are large, operator-reported and unverified — and the privacy price is the reason most democracies stop short of it.
What this route shows
Authority and evidence move in opposite directions here. The systems that only answer or flag can show what they did; the two that act on a whole city report their gains through the vendor or the operator, and nobody outside has checked them.
