The Coasian theory of the program: what is the ideal size?

· Bits and Bobs 11/4/25
  • The Coasian theory of the program: what is the ideal size?
    • The equilibrium size has to do with:
      • 1) Difficulty of producing effective code.
      • 2) Difficulty of distributing the software to users.
    • Historically an app must be somewhat big because software is hard to write, and apps are hard to distribute (on the order of $10 per consumer install).
      • An app has to be big enough to contain within itself a viable business model.
    • But LLMs can produce code cheaply.
      • They are willing to produce itsy bitsy pieces of code that no human would have bothered with if it couldn't be distributed.
      • The code is conceivably correct and useful–but you don't know if it's actually useful to a real human in a real situation yet.
    • The question is what level of program is worth it to bother actually showing to a user to see if it's really useful.
    • If it's useful, it's worth investing resources into distributing to other users.
