Yuval Noah Harari ist der Weltstar unter den Historikern. In «Eine kurze Geschichte der Menschheit» erzählte er vom Aufstieg des Homo Sapiens zum Herrn der Welt. In «Homo Deus» ging es um die Zukunft unserer Spezies. Sein neues Buch schaut auf das Hier und Jetzt und konfrontiert uns mit den drängenden Fragen unserer Zeit. Wie unterscheiden wir Wahrheit und Fiktion im Zeitalter der Fake News? Was sollen wir unseren Kindern beibringen? Wie können wir in unserer unübersichtlichen Welt moralisch handeln? Wie bewahren wir Freiheit und Gleichheit im 21. Jahrhundert? Seit Jahrtausenden hat die Menschheit über den Fragen gebrütet, wer wir sind und was wir mit unserem Leben anfangen sollen. Doch jetzt setzen uns die heraufziehende ökologische Krise, die wachsende Bedrohung durch Massenvernichtungswaffen und der Aufstieg neuer disruptiver Technologien unter Zeitdruck. Bald schon wird irgendjemand darüber entscheiden müssen, wie wir die Macht nutzen, die künstliche Intelligenz und Biotechnologie bereit halten. Dieses Buch will möglichst viele Menschen dazu anregen, sich an den großen Debatten unserer Zeit zu beteiligen, damit die Antworten nicht von den blinden Kräften des Marktes gegeben werden.

"Ich habe dieses Buch, mein ultimatives Notizbuch voller nützlicher Werkzeuge, für mich selbst kreiert. Es hat mein Leben verändert und ich hoffe, dir wird es genauso helfen." TIM FERRISS "In den letzten zwei Jahren habe ich beinahe 200 Weltklasse-Performer interviewt. Die Bandbreite der Gäste reicht von Stars (Jamie Foxx, Arnold Schwarzenegger) und Topathleten bis hin zu legendären Kommandanten von Spezialeinheiten und sogar Schwarzmarkt-Biochemikern. Viele meiner Gäste akzeptierten erstmals in ihrer Karriere ein Zwei-bis-drei-Stunden-Interview. Dieses Buch enthält unverzichtbare Tools, Taktiken und Insiderwissen, die anderswo nicht zu finden sind, außerdem neue Tipps von früheren Gästen und Lebensweisheiten neuer Gäste, die du noch nicht kennst." Was das Buch so außergewöhnlich macht, ist der unablässige Fokus auf leicht umsetzbare Details: - Was tun diese Titanen in den ersten 60 Minuten an jedem Morgen? - Wie sieht ihre Trainingsroutine aus und warum? - Welches Buch haben sie am häufigsten an andere Menschen verschenkt? - Was betrachten sie als die größten Zeitverschwender? - Welche Nahrungsergänzungsmittel nehmen sie täglich? "Alles, was du auf diesen Seiten liest, habe ich in meinem Leben bereits auf die eine oder andere Weise angewandt. Ich habe Dutzende der dargestellten Taktiken bei kritischen Verhandlungen, in riskanter Umgebung oder bei großen Deals eingesetzt. Die Lektionen haben mir zu Millionen von Dollar verholfen und mich vor Jahren verschwendeter Bemühungen und Frustration bewahrt." TIM FERRISS
