This paper studies the impact of artificial intelligence on innovation, exploiting the randomized introduction of a new materials discovery technology to 1,018 scientists in the R&D lab of a large U.S. firm. AI-assisted researchers discover 44% more materials, resulting in a 39% increase in patent filings and a 17% rise in downstream product innovation. These compounds possess more novel chemical structures and lead to more radical inventions. However, the technology has strikingly disparate effects across the productivity distribution: while the bottom third of scientists see little benefit, the output of top researchers nearly doubles. Investigating the mechanisms behind these results, I show that AI automates 57% of "idea-generation" tasks, reallocating researchers to the new task of evaluating model-produced candidate materials. Top scientists leverage their domain knowledge to prioritize promising AI suggestions, while others waste significant resources testing false positives. Together, these findings demonstrate the potential of AI-augmented research and highlight the complementarity between algorithms and expertise in the innovative process. Survey evidence reveals that these gains come at a cost, however, as 82% of scientists report reduced satisfaction with their work due to decreased creativity and skill underutilization.
In the bestselling tradition of Why Nations Fail and The Revenge of Geography, an award-winning journalist uses ten maps of crucial regions to explain the geo-political strategies of the world powers.
All leaders of nations are constrained by geography. Their choices are limited by mountains, rivers, seas, and concrete. To understand world events, news organizations and other authorities often focus on people, ideas, and political movements, but without geography, we never have the full picture. Now, in the relevant and timely Prisoners of Geography, seasoned journalist Tim Marshall examines Russia, China, the USA, Latin America, the Middle East, Africa, Europe, Japan and Korea, and Greenland and the Arctic—their weather, seas, mountains, rivers, deserts, and borders—to provide a context often missing from our political reportage: how the physical characteristics of these countries affect their strengths and vulnerabilities and the decisions made by their leaders.
In ten, up-to-date maps of each region, Marshall explains in clear and engaging prose the complex geo-political strategies of these key parts of the globe. What does it mean that Russia must have a navy, but also has frozen ports six months a year? How does this affect Putin’s treatment of Ukraine? How is China’s future constrained by its geography? Why will Europe never be united? Why will America never be invaded? Shining a light on the unavoidable physical realities that shape all of our aspirations and endeavors, Prisoners of Geography is the critical guide to one of the major (and most often overlooked) determining factors in world history.
Yeah I was super hyped when I saw that announcement. I am excited to see how they portray some of the things in the second and third books (you will know what I mean when you read them) that will require some truly special effects.
I honestly didn't realize how bad this site is until I clicked around a bit and saw all the paywall stuff. I always thought they were scholarly articles, appears not.
Articles from scholarly journals usually cost money. Nature of the beast for narrow-interest publishing with no advertiser support. The fact that Nature links to the source articles is a big plus in my book.
