(Conversation Recorded on August 11, 2022.)

On this episode, we meet with inventor, researcher and author Kris De Decker to understand the concept of “low tech” and its relevance in a high tech society and growth-driven economy.

How does low tech differ from high tech and what does it feel like to live a low tech lifestyle? Why do we assume high tech will always be the solution, and could low tech be a feasible path for a sustainable and fulfilling future?

De Decker shares his personal experiences as a low tech advocate and researcher in a high tech urban environment and how freedom from technology provides both challenges and unexpected benefits.
