Talking Points

Recent interactions between the hosts and their guests.

129. Chain Drain
Q: What role should education play in preparing for these changes?
Education should focus on teaching how to organize teams across disciplines, adopt new data and AI-enabled workflows, and develop degrees (like a Master of Urban Technology) that bridge design, technology, and policy to enable systemic improvement.
129. Chain Drain
Q: What are the four scenarios, and which seems most promising?
The four scenarios—Play, Fast Forward, Pause, and Eject—represent different future configurations; while Play remains common, Eject or Pause offer opportunities to redesign governance and to integrate data and performance across the chain, though they require significant capital and organizational changes.
129. Chain Drain
Q: What is Chain Drain and why does it matter across the AECO supply chain?
Chain Drain describes the disconnection and misalignment across the project lifecycle, from design and planning to construction and operation, which prevents performance data and intended outcomes from flowing through the chain to improve buildings and cities.
130. Build or Die
Q: How do you see the role of regional planning and public engagement evolving to avoid NIMBY opposition?
He argues for planning input at the regional level, using representative sampling and deliberative processes (even jury-like deliberations) to shape rules before individual projects are proposed, reducing adversarial fights at the project level.
130. Build or Die
Q: What are the success stories or green shoots you point to, such as in California or New York?
Ned highlights Transit Oriented Development in California, ULURP reforms in New York, and early rent-price changes in places like Sacramento and Austin as signs of movement towards more effective housing production under new governance and policy approaches.
