Explore the intersection of AI and Scala development in this 40-minute conference talk from Scala Days 2023 Seattle. Delve into the potential impact of AI on Test Driven Development (TDD) methodologies, examining whether AI can effectively write functions and tests. Consider the implications of AI-generated code on API design, test coverage, and the developer's thought process. Investigate the pros and cons of various AI-assisted development approaches, including writing tests before functions, generating complete solutions, and even producing formal proofs. Gain insights into current AI applications in Scala development and contemplate future possibilities. Learn from Bill Venners, president of Artima, Inc., lead developer of ScalaTest and Scalactic, and coauthor of "Programming in Scala, Fifth Edition," as he shares his expertise on this cutting-edge topic.
