This week on the What is The Future for Cities? podcast, we investigated how cities are evolving and what it takes to shape their futures. Episode 329 explored a five-decade analysis of artificial intelligence (AI) in local governance, while Episode 330 featured an insightful interview with Thomas W. Sanchez, Professor of Landscape Architecture and Urban Planning at Texas A&M University. Together, these episodes offered a wealth of knowledge about AI’s transformative potential, the optimism driving urban planners, and the critical balance needed to create sustainable, equitable cities. Here’s what we learned.

The rise of AI in local governance

In Episode 329, we unpacked a comprehensive scientometric analysis titled Artificial Intelligence and the Local Government: A Five-Decade Scientometric Analysis on the Evolution, State-of-the-Art, and Emerging Trends (Yigitcanlar et al., 2024). This research, spanning 1973 to 2023, revealed how AI has moved from a niche concept to a cornerstone of urban governance. The key takeaway? AI’s role in cities is no longer science fiction—it’s here, and it’s growing exponentially.

The study highlighted four main ways AI is transforming local governments: decision support, automation, prediction, and service delivery. For example, early “expert systems” helped planners with tasks like land-use decisions, while today’s AI-powered chatbots, like Los Angeles’ CHIP, answer citizen queries instantly. AI is also optimizing public transport routes, predicting traffic jams, and managing energy grids. These applications show how AI can make cities more efficient and responsive to residents’ needs.

However, the research also pointed out a surprising gap: only 1% of the studies from 1973 to 2004 focused on AI in local governance, with 99% published after 2004. This explosion, particularly since 2014, aligns with advancements in big data, computing power, and machine learning. Emerging trends like geo-AI (using AI for geographic data) and digital twins (virtual city models) are set to further revolutionize urban planning and environmental monitoring.

One critical lesson stood out: while AI’s capabilities are soaring, discussions about ethics, public engagement, and accountability are lagging. Terms like “responsible AI” are starting to appear, but they’re still a small part of the research. This gap raises a vital question: how can cities harness AI’s power without creating new biases or eroding trust? The episode encourages us to prioritize transparency and inclusivity as AI becomes a bigger part of urban life.

The planner’s optimism and vision for cities

In Episode 330, Thomas W. Sanchez shared a compelling vision of cities as “systems of systems”—complex networks of social, economic, and physical elements that enable humanity to thrive. His perspective as a planner and educator brought a human-centered focus to the conversation, emphasizing the role of optimism, history, and technology in shaping urban futures.

Sanchez described cities as the “brain” of human civilization, where ideas connect and creativity emerges, much like neurons firing in our minds. This metaphor underscores why cities are hubs for innovation, but also why they’re vulnerable to disruptions like pandemics or climate change. He stressed that planners must think beyond short-term fixes, imagining cities over “geologic time”—decades or centuries—to spot patterns and make smarter investments in infrastructure and design.

A standout lesson from Sanchez was the innate optimism that defines planners. He explained that planners enter the field with a belief that “we can make this work,” even when facing daunting challenges. This mindset isn’t naive; it’s tempered with realism and a commitment to learning from the past. For instance, Sanchez noted that humans often repeat historical mistakes, like ignoring environmental warnings or perpetuating inequities. By studying history, planners can break these cycles and design cities that are more resilient and inclusive.

Sanchez also redefined technology as “doing things in a new way,” whether it’s a plow, a pencil, or AI. His upcoming book, AI for Urban Planning (Routledge, 2025), explores how AI can enhance decision-making by synthesizing vast amounts of data. However, he cautioned that technology’s value depends on its impact—innovations must be evaluated over time to ensure they benefit everyone. This perspective aligns with Episode 329’s call for ethical AI, reinforcing the need to balance progress with responsibility.

Key takeaways for urban futures

So, what can we take away from this week’s episodes? Here are four big lessons:

AI is transforming cities, but it’s still young

AI is already streamlining city services, from chatbots to traffic predictions, and emerging tools like geo-AI and digital twins promise even more. But its rapid growth—99% of research since 2004—means we’re still figuring out how to use it effectively. Cities must invest in AI thoughtfully, ensuring it serves residents without leaving anyone behind.

Optimism fuels progress, but history guides it

Sanchez’s optimism reminds us that belief in a better future drives urban innovation. Yet, as both episodes emphasized, learning from history is crucial to avoid repeating mistakes. Whether it’s addressing climate change or reducing inequities, cities must blend hope with evidence-based planning.

Cities are systems, and everyone has a role

Sanchez’s “systems of systems” view shows that cities thrive when all parts—people, infrastructure, technology—work together. His call to spread excitement about urban planning invites everyone to participate, whether through civic engagement or simply imagining what their city could become.

These episodes challenge us to think bigger about our cities. AI offers incredible tools to make urban life more efficient and sustainable, but it’s not a magic fix. Planners, policymakers, and citizens must work together to ensure technology serves the greater good. Meanwhile, Sanchez’s optimism inspires us to stay hopeful, even when the path forward feels uncertain. As he put it, cities are where humanity clusters—our future depends on making them places where everyone can thrive.

What’s the most exciting idea you’re taking away from this week?

Maybe it’s the potential of geo-AI to map urban challenges, or the planner’s belief that “we can sort this out.” Whatever it is, let’s work together for a better tomorrow.
