This is the book to hand your teen who's glued to their phone and considering a CS major—or any adult who's ever wondered why that signup form won't accept their name.

Wachter-Boettcher delivers a readable, well-researched tour of tech's ethical blind spots, from algorithms that discriminate to interfaces that assume everyone is a straight white dude. The examples are concrete and often infuriating (social media reminders about dead relatives, anyone?), making abstract concepts like algorithmic bias suddenly very real.

It's not a kids' book, but it's an excellent resource for older teens developing critical thinking about the technology they use daily. The 2017 publication date means some examples feel slightly dated, but the core problems remain depressingly current. Think of it as essential digital literacy for the smartphone generation—and their parents who need to understand what's really happening behind those friendly app interfaces.
