# Intelligence > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] places this node within the history and governance of substrate-independent evolution. **Domain:** Cognitive Science / AI / Biology **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition Intelligence is the capacity to learn, infer, adapt, plan or solve problems across environments; no single definition exhausts biological and artificial cases. ## Three Meanings The word also carries two institutional meanings that must remain distinct from cognitive capacity: - **intelligence as production:** [[wiki/Intelligence Production Chain|the transformation of observations into evaluated, provenance-bearing, actionable understanding]]; and - **intelligence as institution:** the [[wiki/Intelligence Community|United States Intelligence Community]] charged with producing national-security intelligence. These meanings are converging on a shared computational substrate because [[wiki/Artificial Intelligence|AI]] increasingly performs parts of the production chain inside IC systems. Shared substrate does not make cognitive capability, an intelligence product, and an intelligence institution the same kind of entity. ## Nexus Context The article shows that universal computation, self-replication and Darwinian evolution are separable from intelligence. Evolution can produce adaptive complexity without any individual reasoning. ## Evidence Boundary Performance can evidence competence without settling consciousness or moral status. Rights analysis must not use intelligence as the sole proxy for experience or personhood. ## Relationships [[wiki/Artificial Intelligence|Artificial Intelligence]], [[wiki/Intelligence Production Chain|Intelligence Production Chain]], [[wiki/Intelligence Community|Intelligence Community]], [[wiki/Machine-Readable Assurance|Machine-Readable Assurance]], [[wiki/Consciousness|Consciousness]], [[wiki/Sentience|Sentience]], [[wiki/Universal Computation|Universal Computation]] ## Simple Reminders, Quotations, and Thoughts > "Something about discussion of artificial intelligence appears to displace human intelligence." > **— Neil Gershenfeld**, *2015, Edge annual question “What Do You Think About Machines That Think?”* [[reminders/Machine Succession/AI Debate Can Displace Human Intelligence by Neil Gershenfeld|AI Debate Can Displace Human Intelligence by Neil Gershenfeld]] > "The rapid advance of AIs also is changing our understanding of what constitutes intelligence." > **— Paul Saffo**, *2015, Edge annual question “What Do You Think About Machines That Think?”* [[reminders/Information/AI Is Changing What Intelligence Means by Paul Saffo|AI Is Changing What Intelligence Means by Paul Saffo]] > "Taken together there is nothing like "intelligence" which can be extracted as a precise concept and which can be used as a reference for "artificial intelligence"." > **— Ernst Pöppel**, *2015, Edge annual question “What Do You Think About Machines That Think?”* [[reminders/Risk Debate/Intelligence May Be Too Imprecise to Artificially Reproduce by Ernst Pöppel|Intelligence May Be Too Imprecise to Artificially Reproduce by Ernst Pöppel]] > "SETI is uniformitarian in its assumption that all alien intelligence would be the same, namely, like human intelligence (but smarter, of course)." > **— Ian Bogost**, *2015, Edge annual question “What Do You Think About Machines That Think?”* [[reminders/Machine Succession/SETI Assumes Alien Intelligence Resembles Ours by Ian Bogost|SETI Assumes Alien Intelligence Resembles Ours by Ian Bogost]] > ""Thinking" is a word we apply with no discipline whatsoever to a huge variety of reported behaviors." > **— James J.
