This is todays edition ofThe Download,our weekday newsletter that provides a daily dose of whats going on in the world of technology.Why we need an AI safety hotlineKevin Frazier is an assistant professor at St. Thomas University College of Law and senior research fellow in the Constitutional Studies Program at the University of Texas at Austin.In the past couple of years, regulators have been caught off guard again and again as tech companies compete to launch ever more advanced AI models. As it stands, it seems theres little anyone can do to delay or prevent the release of a model that poses excessive risks.Existing measures to mitigate AI risks arent enough to protect us, so we need new approaches. One could be a kind of AI safety hotline tasked with expert volunteers. Read more about how the hotline could work.African farmers are using private satellite data to improve crop yieldsIn many developing countries, farming is impaired by lack of data. For centuries, farmers relied on native intelligence rooted in experience and hope.Now, farmers in Africa are turning to technology to avoid cycles of heavy crop losses that could spell financial disaster. Theyre partnering with EOS Data Analytics, a California-based provider of satellite imagery and data for precision farming, which allows them to track where or when specific spots needed attention on various farmsand even to anticipate weather warnings.

Stallman, then a 27-year-old programmer at the university.A few years later, Stallman released GNU, an operating system designed to be a free alternative to one of the dominant operating systems at the time: Unix. The free-software movement was born, with a simple premise: for the good of the world, all code should be open.Forty years later, tech companies are making billions on proprietary software, and much of the technology around us is inscrutable. But while Stallmans movement may look like a failed experiment, the free and open-source software movement is not only alive and well; it has become a keystone of the tech industry.
