What makes you think people can build superhuman AI when they don’t even understand intelligence?
Past AI progress hasn’t required much understanding of intelligence.
As explained in Chapter 2, the AI field has achieved its recent feats by employing gradient descent, a process that does not require humans to understand intelligence. Humans have gotten really quite far without needing to understand intelligence.
Natural selection didn’t need to “understand” intelligence.
Evolution was able to produce human intelligence just fine without natural selection ever understanding intelligence. Understanding may or may not be helpful in practice, but the idea that we need to understand it to produce it doesn’t hold water.
