from Robin Hanson Of Overcoming Bias blog:

I have learned most of the list from other places but I learned the following from the article.

5. Innovation in large systems comes mostly from part innovation, so system innovation is steadier than part innovation, and the largest systems grow steadiest.

6. System structures vary in how well they encourage and test innovations locally and then distribute the best ones widely. Better structures for this are meta-innovations.

  • Good modularity reduces the need to match innovations in differing parts.
  • Good abstraction puts similar innovation problems within the same part.
