Despite the advantages new technologies have afforded us recently, the question of what role technology should play in our lives remains an urgent one. Unfortunately, control over these technologies, the management of them and creation of new ones, relies on a small, sometimes invisible, minority of Silicon Valley engineers whose decisions are at best opaque, at worst, seemingly devoid of human understanding or empathy. Even in the cases where the founders and CEOs are well-intentioned, the majority seemed to have failed to take into account the unintended by-products their technologies have foisted on us. Their choices drive culture, behavior, policy, elections, even wars. Through eye opening stories, System Error exposes that mindset and shows how its myopic focus on algorithmic success at all costs results in the sacrifice of fundamental human values.
