Why it worked
The video leverages the intrigue of a well-known figure (Gabe Newell) undertaking an unusual and expensive project (deep-sea exploration yacht) and frames it as a philanthropic endeavor by open-sourcing the research, which appeals to a sense of curiosity and potential societal benefit.
Summary
The video discusses how billionaire Gabe Newell, creator of Steam, spent $800 million on a new yacht not for luxury, but to explore the deep ocean. He is open-sourcing all data and discoveries from this project to scientists, making it a unique endeavor that even large companies cannot afford.
