Something that has become interesting to me recently is the amount of knowledge about maratime weather and sailing that isn't readily accessible in a some kind of neat database, app or website. You actually have to talk to people and wander through museums to find out some of it.
It's an example of an industry and body of knowledge that still grows and is passed around outside of the internet.
Weather patterns for a particular area, places to anchor and dock, safe passages through reefs. You can't always google the answer and much of it is gleaned from other sailors who used experience and their tools to figure it out.
Having grown up pretty much constantly online, with the answer to any question I have being reasonably available with a quick search; that some common information about the world can still be discovered and shared is is really fascinating.
It sometimes feels like there isn't much outside of STEM fields left to explore.
