as machine learning and neural networks, to solve complex analytical problems in commerce, industry, and government. Organizations use enterprise AI software to increase efficiencies, reduce costs, and improve operations. The US Air Force, for example, uses AI to predict engine failure in aircraft before a failure occurs in order to improve maintenance and increase aircraft readiness. Digital transformation Siebel's fourth book, Digital Transformation, became a Wall Street Journal bestseller in July 2019. In the book Siebel discusses how the confluence of four modern information technology vectors—elastic cloud computing, big data, artificial intelligence, and the internet of things—is impacting business, government, and society. He characterizes the 21st century as a period of corporate mass extinction. He states that since 2000, 52 percent of Fortune 500 companies have fallen off the list, and he discusses how new companies like Amazon, Uber, Tesla, Airbnb, and others have emerged and grown during this time. Siebel claims that in order to survive and thrive in the 21st century, organizations must undergo digital transformation by harnessing the four information technologies discussed in the book. The book provides advice to organizations in the form of a 10-point CEO action plan. Management philosophy Siebel is a proponent of building a “self-learning corporate culture” that motivates employees to continue their education on the job. C3.ai offers cash awards of $1,000 to $1,500 to employees for each course they complete from a curated Coursera curriculum. In 2019, Siebel initiated a program at C3.ai that pays 100 percent of the costs for employees to complete an online master's degree of computer science (MCS) program from the University of Illinois at Urbana-Champaign. Employees who complete the MCS degree receive a salary increase of 15 percent, a cash bonus of $25‚000, and additional stock options.
