10 years ago, social media was exciting. Social media let you see content from people you cared about. Then came "influencers" and now comes AI-generated junk. Multi-billion-dollar businesses now depend on history not repeating itself.
In my great grandparents era, getting a letter in the mail was exciting. Then came bills and marketing junk mail.
In the 1960/70s, CB radio was exciting; then it turned into a cesspool.
40 years ago, getting a phone call was exciting. Then came free international calls and junk robo calls, and now people don't even answer the phone.
35 years ago, usenet was exciting, then came spam, 1990's-era "me too" posts, and AOL users. And usenet became useless.
30 years ago, email was exciting. Then came "legitimate" marketing mails and illegitimate spam, and email is nearly useless and certainly not fun.
