Topic: Phoebus Cartel

One host describes the "bionic" experience of recovering from cataract surgery, noting the extreme brightness of the world with a new lens. This leads to a discussion on the history of planned obsolescence in the light bulb industry, referencing the Phoebus Cartel, and providing technical advice on buying high-efficiency LED grow bulbs.

The hosts explore the history of the Phoebus Cartel, a group of light bulb manufacturers in the 1920s that conspired to limit the lifespan of bulbs to 1,000 hours. They contrast this with the "Livermore light bulb," which has burned for over 110 years. The segment discusses how planned obsolescence has become a fundamental part of the modern economy, from iPhones to household appliances.
