I'm in my mid 20s, far from being a grumpt old man, and I used to frequent Facebook back in the early 2010s (remember all those games?)
What became clear is how the landscape is filled to the brim with scammers and grifters. These newer applications of technology are akin to cigarettes, or heroin, or opium. They're designed to inflict misfortune for profit.
Years ago my parents would chastise me for spending too much time othe computer/phone, now I'm the one begging them to uninstall those garbage applications from their phones.
Around me, more older people than younger ones are susceptible to lies and scams perpetrated by LLMs.
The younger generation around me (kids 10 to 17 yo) are falling for the same traps I fell for when I was their age, and people my age are stil falling for: addictive online games with scummy lootboxes (especially Fifa) and gacha games.
I believe there are more than enough studies detailing the extreme negative consequences of Instagram and/or tiktok usage, so much that we don't question that anymore, and treat it like ye olde tobacco addiction. It's addicting and fucks up your health but here yo stay.
