Kris De Decker: “Low Tech: What, Why and How”
Episode 33
August 24, 2022
(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.
