Amjad Masad demos building and deploying a feature-request dashboard in minutes, highlighting how Replit abstracts away setup, hosting, databases, and most coding. He and Lenny then dig into how this changes the roles of engineers, product managers, designers, and founders—shifting constraints from implementation capacity to idea generation and iteration speed.
