Birds, Brains, Planes, and AI: Against Appeals to the Complexity / Mysteriousness / Efficiency of the Brain
[Epistemic status: Strong opinions lightly held, this time with a cool graph.] I argue that an entire class of common arguments against short timelines is bogus, and provide weak evidence that anchoring to the human-brain-human-lifetime milestone is reasonable. In a sentence, my argument is that the complexity and mysteriousness and efficiency of the human brain (compared to artificial neural nets) is almost zero evidence that building TAI will be difficult, because evolution typically makes things complex and mysterious and efficient, even when there are simple, easily understood, inefficient designs that work almost as well (or even better!) for human purposes. In slogan form: If all we had to do to get TAI was make a simple neural net 10x the […]
