Hey now, the hipsters of the baby boom invented rock and roll, and sex, and drugs. Well of course they would have had to be 3 years old in 1948 to invent rock and roll, and sexual liberation had been pushed for decades (check 1920s Germany), and even LSD went back to 1938 and Ectasy back to the 1910s. Cocaine and pot before that. But they can’t dream and boast, can’t they?
They didn’t invent it, but they sure helped make it mainstream in the US. :-)
