The presentation by Ryan Kennedy explores the concept of fear in software development, highlighting how fear can lead to negative emotions that affect performance, decision-making, and agility. It discusses common fears among developers, including refactoring and deploying, and presents strategies for overcoming these fears such as exposure therapy, extensive testing, and open communication. Ultimately, it emphasizes the importance of addressing fear to foster a healthier, more productive engineering environment.
