This is of course the famous quote from Socrates, and I absolutely hate this "argument". "Socrates was wrong in 400BC and it's wrong today" is one possible scenario, but it's also entirely possible that:
- Socrates was right in 400BC.
- at multiple points in 2,400 years there was a problem with "kids these days".
- Socrates was wrong in 400BC, but it's fair today or at other points in history.
It's just a complete non-argument.
Edit: and according to a sibling comment it's not even a genuine quote, but that doesn't matter: it's a non-argument whether it's a genuine quote or not.
The same applies to this "list", which is not a "long history" but just 19 quotes from the last 19 years from random people. Maybe some had a point and some didn't? Maybe none did? Maybe all did? That 19 people about of several hundred million complained about something (fairly or unfairly) in the last 19 years is just a non-argument.
