OK, I’m still impressed! :^)
As you say, a lot of “knowledge” is knowing where & how to find the relevant info, quickly when necessary. The Internet has made a lot of that easier, but there are mountains of irrelevant stuff too, so it takes a practiced mind and touch to burrow though it efficiently.
Our job has been made a whole lot easier by the internet. I remember the days when we had to do legal research in actual books, with huge volumes of Shepard's Citations and Digests and Encyclopedias to try to organize the case reports in some way. Individual word search has made the whole thing a breeze, compared to the bad old days. I was one of the first people to use the very first LEXIS terminal in Atlanta -- it was a stand alone linked to the mainframe in Wisconsin, in the District Courthouse on Spring Street, and they installed it in 1980 or 1981 IIRC. So I've had lots of practice with Boolean logic.
Same for genealogy. Of course, since the genealogy sites aren't funded and standardized like the law research sites, there are many errors out there, even in the LDS stuff which is pretty solid.
But it sure beats the days of hanging around in the basements of courthouses all across Georgia and Alabama, among the dusty old books and crazy old ladies in tennis shoes (but I did that too, I was just a crazy YOUNG lady at the time! And everybody wore tennis shoes because those concrete floors would kill you if you wore pumps.)
