90s: stay anonymous, be careful with strangers, don't give up any more info than you have to. The internet can be a dangerous place. Also, supervise your kids and have them ask permission to go online.
2010s-2020s: livestream your life 24/7, use real names and emails everywhere when signing up for bullshit, hand your kid a phone and let them go buck wild as well.
How did we stray like this?
