The document compares the evolution of Silicon Valley to Hollywood and notes several similarities that have emerged: - Both became major industry clusters centered around specific locations and expertise - As the industries grew, surrounding ecosystems developed including agents, lawyers, investors and other hangers-on not directly involved in production - There is now more focus on founders and CEOs as brands and personalities, driven partly by ego and vanity, rather than just the work itself The key message is that Silicon Valley has transitioned from being solely about the technical work to also having a "star ecosystem", and entrepreneurs should focus on building great products rather than getting distracted.
