21 Lessons for the 21st Century

By Yuval Noah Harari

    Humans have irreversibly changed the world. This book explores the ways in which we have done so, in ways that many may not even realize, and explains the impacts of these changes on the future.
    The first few chapters discuss how AI and computers have progressed. They are slowly taking over jobs that normally would have required humans, and though they may never gain full "consciousness", which is something that even people don't really understand, they will have significant impacts on humans and the workplace. Because of these rapid changes, the job market will also fluctuate rapidly, which means that the traditional model of education may not work anymore. It might no longer make sense to learn basic skills then train your entire life for one occupation. Instead, dynamic learning, constant retraining for new jobs, might be necessary. Connecting to the idea of AI, the future might also be shaped by computers. Algorithms are already getting better than even humans at detecting user interest - perhaps in the future, Google or Facebook will know you better than you do yourself.
    Part two discusses politics and religion. Nationalism is a big thing these days, and while humans always tend to gather into groups, ultra-nationalism is dangerous. It is what causes war and division, but the world needs to collaborate to succeed.
    Part three is about war and peace (no not the book). It first delves into terrorism, and how it has changed our world. In the past, terrorists would have had no impacts at all. But we have gotten so used to being perfectly safe that even the slightest tremors make us afraid, make us overreact, which is exactly what the terrorists wanted in the first place. As for war, in today's world, war for big countries means mutually assured destruction. But one should never underestimate the stupidity of humankind, when one misstep could cause catastrophe. And that is why a little humility would be good for everyone.
    The final parts discuss how, in the digital age, humanity as a whole has gained massive knowledge but individuals know less and less because so much easy information is at our fingertips. And this is why fake news is so dangerous.
    Many think that life is a story that you are the center of. But it's not. So just take a step back and reflect, observe, and meditate.

Note: I've read so many books by this person and I'm a little bored...
