According to AI, the future is bright. The prompts focused on how overcrowding, climate change and technological development are likely to change the cities of the future. The amazing results show many of the concrete jungles adorned with lush vegetation sprouting from sci-fi-looking hi-rises that winged vehicles soar around in bright blue skies. By 2050, almost three-quarters of the world population (68 percent) will live in cities, according to a UN prediction. While it might sound bleak, technology could turn congested regions into lush utopias.

In his book "Life 3.0", MIT professor Max Tegmark says "we are all the guardians of the future of life now as we shape the age of AI." Artificial Intelligence remains a Pandora's Box of possibilities, with the potential to enhance the safety, efficiency, and sustainability of cities, or destroy the potential for humans to work, interact, and live a private life. The question of how Artificial Intelligence will impact the cities of the future has also captured the imagination of architects and designers, and formed a central question to the 2019 Shenzhen Biennale, the world's most visited architecture event. As part of the "Eyes of the City" section of the Biennial, curated by Carlo Ratti, designers were asked to put forth their visions and concerns of how artificial intelligence will impact the future of architecture. Below, we have selected six visions, where designers reflect in their own words on aspects from ecology and the environment to social isolation. For further reading on AI and the Shenzhen Biennial, see our interview with Carlo Ratti and Winy Maas on the subject, and visit our dedicated landing page of content here.

The way that people get around cities is changing dramatically. Technological advances and new transportation services are making it possible for city dwellers to cross town ever more efficiently and safely. These shifts could have profound economic and social effects. McKinsey analysis indicates that in 50 metropolitan areas around the world, home to 500 million people, integrated mobility systems could produce benefits, such as improved safety and reduced pollution, worth up to $600 billion. Because each city is unique, the transition to integrated mobility will also play out differently, and produce different results, from one city to the next.

All too often we see yet another startup appearing on the scene concentrating on a solution to a problem that doesn't exist. Before you can mutter the digital mantra "technology for technology's sake," it disappears, never to be seen again. Frontdoor doesn't seem to be one of those startups. Co-founder Alain Kapatashungu and his team of city dwellers had grown frustrated with how tedious the old way of searching for an apartment had become. Their research taught them that renters take on average 5,040 minutes to find an apartment, 45 percent of inquiries never receive a reply and a disturbing 50 percent of listings were either fake or scams.
