Episode notes
What A Platform Really Is
- A platform is any space or technology that facilitates transactions between groups of people.
- The nature of that space largely determines how wealth and freedom distribute in a civilization.
Amazon's Shift From Marketplace To Tax
- Tim traces Amazon from a bookstore to a dominant marketplace that began as a decentralizing force.
- Over time Amazon raised fees and developed advertising as a high-margin extractive product that harms independent sellers.
Regulate To Preserve Innovation
- Balance the positive gains of platforms with rules that limit their extractive power.
- Use retrospective tools like antitrust and prospective regulation tailored to novel risks like AI.
