Talking Points

Recent interactions between the hosts and their guests.

#68 - Haris Piplas: "Co-opetition" and the honest city - what urban regeneration should and shouldn't be
Q: Haris, could you tell me a bit about your time growing up in Sarajevo and Berlin and how that shaped your view of cities?
Growing up exposed to diverse cultures and conflict, I learned that cities are porous systems where geopolitics, finance, and culture intersect; this shaped my belief that urban transformation must be inclusive, context-specific, and grounded in long-term social and environmental outcomes.
#67 - Anastassia Lauterbach: Literacy before fluency, why AI is not a religion and the brain needs training
Q: Given the prevalence of AI hallucinations, how should organizations approach AI integration responsibly?
Organizations should implement domain-specific checks, human-in-the-loop processes, and cautious governance that aligns with real-world context, rather than relying solely on large, opaque models.
#67 - Anastassia Lauterbach: Literacy before fluency, why AI is not a religion and the brain needs training
Q: What distinguishes AI literacy from AI fluency, and why does it matter for education and governance?
Literacy covers the fundamentals—data provenance, model capabilities, and governance—while fluency focuses on practical tool use and prompting. Both are necessary to set realistic expectations and to empower individuals to make informed decisions about AI deployment.
#52 - Makoto Kern: Feature-centric to user-centric - UX Design to navigate global challenges and the “AI Competence Mirage”
Q: Can you explain the difference between UX and UI and why it matters in practice?
UX is about the end-to-end user journey and how easily users achieve their goals, while UI is the visual layer; great UX can exist with simple visuals, and even a visually strong interface can fail if the underlying workflow is poorly designed.
#49 - Nadja Kunz: Towards water stewardship in mining, understanding critical minerals, safer and sustainable resource management
Q: What does the word innovation truly mean in your work and how has it shaped your challenges?
Innovation means not just having ideas but implementing them with supporting systems to move them forward, turning concepts into action.
