Fung explains that AI has enabled her team to ship 8x more code, changing the role of engineers from coders to creative builders and deep systems experts. She emphasizes the importance of a growth mindset, high agency with accountability, and using AI routines to automate management tasks like code review and feedback processing. The conversation covers the shift from vanity metrics like token usage to measuring true ROI, and the 'bad vs. sad' framework for balancing speed and quality. Fung discusses how Anthropic uncovers latent demand by observing unexpected user behaviors, and how roles like PM and data science are evolving as AI blurs traditional boundaries. She highlights the challenge of increased context switching with multiple AI agents and the need for just-in-time planning over long roadmaps. Key concerns include preventing skill atrophy through pair programming and hackathons, and preserving team culture during rapid scaling by being transparent about struggles.
