I let my friend’s 9-year-old kid use the janky time machine to go have some fun for the afternoon. In this timeline, kids use child tracking wristbands, or CT Bands, that allow parents to outsource their helicopter parenting instincts.
Once her son turned 8 he got his non-driver’s license, and he’s been out and about every day, ever since, with only two rules. Don’t do anything stupid, and come home before the streetlights turn on. Both of which, among myriad other security vectors, are monitored and managed by the CT Band and its autonomous vehicle uplink.
