Sometimes ethical AI can be achieved by a slight change in perspective

The Barcelona city website's blog discusses how the city is implementing artificial intelligence in a way that protects health and safety while also protecting citizens' rights. Each of these projects is highly valuable, but the third project stood out to me for its novelty. The city needed to ensure that its beaches were not overcrowded. They could have used an AI facial recognition algorithm to scan the faces of every person who entered a beach. Instead, they used thermal image processing to assess which parts of the beach were full.
