I think what he means is other people that have produced substantial works like books etc that are the actual resources you need to consume in order to gain the knowledge. Google helps you find peoples opinions of what good resources are to dive deep on a topic so you can then acquire and consume them.
Sometimes you can get linked directly to a great resource but IMHO the best stuff costs money and is usually worth it for the results that that particular incentive structure engenders.
I know this is a shorthand heuristic but Google helps you _find_ other people that can help you learn new things and develop foundational knowledge.
The map is NOT the terrain.
