David Krakauer at the Santa Fe Institute makes a useful distinction about this generational compact. A tool, he says, is complementary if the underlying capacity persists, or is even enhanced, when the tool is removed — think of the gym that builds our muscles and our friendships. A tool is competitive when the capacity degrades because we used it to achieve a goal. Imagine a gym that holds a competition for who can lift the most weight, and then we send robots with our gym cards to lift for us. The robots are very impressive — superhuman, super-intelligent — but in the end our muscles atrophy and we make no friends. That is a competitive tool: it makes our capacity degrade once it is removed.
