The new agile approach to the planning of the cities of the future seems to be ideal thanks to three tools for better planning: Data that we can use to develop artificial intelligence, balanced partnerships that support participation and fair data economy, and experimentation that helps us to look into future. The vision of a data-driven city is to change the operational model of the city to digital in the era of artificial intelligence. Such a digital operating model can handle any emergency situation, because it can efficiently redirect resources and does not need to involve people of flesh and blood for simple operational tasks - intelligent algorithms are sufficient. Presentation will also provide practical examples of better planning and what works in practice, but also what are the risks of this approach and what we must avoid in the future.
