If we're not intelligent then the term is meaningless. And we're more that just a search engine (well, you might not be) because we have self awareness (yes, we do , its not an "illusion" as some idiots claim because otherwise who or what is the illusion fooling?)
"Many (most?) have labored under the hubris that there is something mysterious and unattainable about the human mind"
Few people claim that. What they do claim is that the human mind is way more complicated than was assumed plus it works in a different way to ANNs anyway - biological brains do not use back propagation. What they do use in lieu of it isn't really understood plus its not only the neurons that affect brain state and operation. White matter and various chemicals plays a big part too.
