Kids definitely have a different(extreme.. worse..) experience today, I'm not going to argue with that. But I think I was 5 when I started going long stretches of the day with no parental involvement and large amounts of device time. When I was 12 I got a modem, and was suddenly exposed to porn, online socializing and trolling, underground culture, pirated games, etc. For large stretches of time it was basically all I did outside of poorly performing at school.
