Social and business history repeat constantly.
Both the 1920s and 1960s featured rebellious youth (the girls suddenly donning daring short skirts) dancing lascivious dances to odd rhythms derived from black-influenced music while devouring illegal substances.

Religious movements sweep through the country in regular waves, usually accompanied by an “anti” crusade: abolitionism, temperance, anti-drugs, anti-abortion.
Controversies over milk in the late 19th century are eerily similar to controversies over milk in the late 20th century, both involving the health and safety aspects of milk, and whether breastfeeding should be encouraged over formula.
The English language has been declining and been being destroyed by lazy speakers every single year since the birth of the republic.
Any good social historian should be able to come up with hundreds more examples, so many that all adults who’ve lived to the age of 50 should just roll their eyes whenever anyone starts spouting off about how the latest new thing is so different from when they were young. Somehow they don’t, continually being surprised by the obvious.
So while the Internet was a New Thing, the response to it could and should have been precisely foretold by any and all sociologists, historians, and business leaders. (Some did, to be sure, getting themselves insulted by the true believers.) But that’s why a study of history is a very good thing, indeed, little as it might appear so in high school. I read more history every year; it’s a neverending source of fascination.
