Bill Gates reveals his 5 favorite books he read in the past year

Paul Scharre's book, Army of None, explores a timely and important question: Why should we put computers in charge?

In an age where autonomous weapons can be programmed to wipe out human targets, many anticipate a future of needless killings and civilian casualties. Army of None makes the case for combining artificial intelligence with our own judgment, so that no algorithm can make the final call on a human life.

Gates said the book filled a void in his canon.

"My first attempt to educate myself on autonomous weapons was a bust," he wrote. "I read a book that was dry and felt really outdated. Then a few months ago I picked up Army of None...It's the book I had been waiting for."

Fans of the Netflix documentary Wild, Wild Country will enjoy Tara Westover’s memoir, Educated, the story of a woman raised in a Mormon survivalist home. As a child, Westover grew up under the influence of her conspiracy theorist father, who believed that doomsday was upon them.

Despite never having stepped foot in a classroom until age 17, Westover was able to study enough to gain admission to Brigham Young University. From there, she earned a Gates Scholarship (a fact Gates himself discovered upon reading her book), which brought her to Cambridge University.

Her tale is one of trauma, separation, and, ultimately, self-discovery. It also touches on the polarization in America between red and blue states, rural and urban areas, and college-educated citizens versus those without a higher degree.

When Gates spoke with Westover about this subject, she had this to share: "I worry that education is becoming a stick that some people use to beat other people into submission or becoming something that people feel arrogant about," she said. "I think of [it] as this great mechanism of connecting and equalizing."

Gates said the title of historian Yuval Noah Harari's latest book is a misnomer.

"Although you will find a few concrete lessons scattered throughout, Harari mostly
resists handy prescriptions," Gates wrote.

Instead, it encourages people to practice mindfulness and meditation when faced with some of the world's most pressing problems, like terrorism and inequality.

Though Gates takes issue with a few arguments — including the idea that social media has prompted our political polarization — he embraces the idea of tempering our worries amid life's greatest challenges.

He also came away with his own life lesson: "I have to be careful not to fool myself into thinking things are better — or worse — than they actually are."

Continuing with the theme of mindfulness, Gates' final recommendation provides research-based evidence of why meditation is such a powerful tool for eliminating distraction.

The book's author, Andy Puddicombe, is an ordained Buddhist monk who went on to co-found Headspace, a popular meditation app featuring guided practices, animations, articles, and videos.

Gates refers to Puddicombe as "the person who turned me from skeptic to believer." He even asked Puddicombe to spend a day and a half walking his family through meditation exercises.

"I'm not sure how much meditation would have helped me concentrate in my early Microsoft days," Gates wrote. "But now that I'm married, have three children, and have a broader set of professional and personal interests, it's a great tool for improving my focus."
