I had a manager at my first job at 14 (so about '96) and she must've been in her 20s or 30s (hard to tell, I feel like the age of adults was difficult to gauge at that age) who had no idea who Jimi Hendrix was. I'm sure she heard his music in passing or in a movie or something. But absolutely no idea. 14 year old me who played guitar and loved my heroes was stunned - completely shocked. Then I grew up and am no longer shocked. The world isn't catered to my tastes and knowledge bank, and that's a good thing.
