In her concise, compelling book, Wachter-Beottcher lays out the danger and the insensitivity of biased algorithms, alienating online forms, and harassment-friendly platforms in the tech industry. As designers and developers, we put too much assumptions into the users without understand their circumstances. We place cleverness over clarity. As demonstrated examples after examples in the book, the results of these poor-designed decisions are unfortunate and tragic. It’s an important read for those of us who truly care about our users.
