AI Superpowers: China, Silicon Valley, and the New World Order
AI Superpowers: China, Silicon Valley, and the New
THE NEW YORK TIMES, USA TODAY, AND WALL STREET JOURNAL BESTSELLERDr. Kai-Fu Lee—one of the world’s most respected experts on AI and China—reveals that China has suddenly caught up to the US at an astonishingly rapid and unexpected pace. In AI Superpowers, Kai-fu Lee argues powerfully that because of these unprecedented developments in AI, dramatic changes will be happening much sooner than many of us expected. Indeed, as the US-Sino AI competition begins to heat up, Lee urges the US and China to both accept and to embrace the great responsibilities that come with significant technological power. Most experts already say that AI will have a devastating impact on blue-collar jobs. But Lee predicts that Chinese and American AI will have a strong impact on white-collar jobs as well. Is universal basic income the solution? In Lee’s opinion, probably not. But he provides a clear description of which jobs will be affected and how soon, which jobs can be enhanced with AI, and most importantly, how we can provide solutions to some of the most profound changes in human history that are coming soon.

The Business Solution to Poverty: Designing Products and Services for Three Billion New Customers
The Business Solution to Poverty: Designing Products and
Right now the number of people living on $2 a day or less is more than the entire population of the world in 1950. These 2.7 billion people are not just the world’s greatest challenge—they represent an extraordinary market opportunity. By learning how to serve them ethically and effectively, businesses can earn handsome profits while helping to solve one of the world’s most intractable problems. The key is what Paul Polak and Mal Warwick call Zero-Based Design: starting from scratch to create innovative products and services tailored for the very poor, armed with a thorough understanding of what they really want and need and driven by what they call “the ruthless pursuit of affordability.”Polak has been doing this work for years, and Warwick has extensive experience in both business and philanthropy. Together, they show how their design principles and vision can enable unapologetic capitalists to supply the very poor with clean drinking water, electricity, irrigation, housing, education, healthcare, and other necessities at a fraction of the usual cost and at profit margins attractive to investors. Promising governmental and philanthropic efforts to end poverty have not reached scale because they lack the incentives of the market to attract massive resources. This book...
