How did we ever get along before the Internet in general and YouTube?
I was a museum professional, historian and writer by profession. Back in the 70s, 80s, and 90s research required hours of digging through library/historical society card catalogues, many long distance calls, numerous letters, hundreds of miles of driving and sometimes cross country flying to do research. Now, nearly everything I was researching is available on line or at least the indexes are. Now, some of my work is available on line.
Yes, YT and the Internet are wonderful tools. I wonder how many thousands of dollars they have saved us in the last 10 years building things, fixing things and buying things.
