A conference talk by Derek Bingham exploring how software developers should adapt to the rise of AI coding assistants and agentic workflows. Starting from a personal story of building a Pac-Man/Snake hybrid game with his son using an AI agent, Derek covers the evolution of developer tooling from VI to multi-agent systems. Key practical advice includes context engineering over prompt engineering, managing LLM context windows effectively (chunking tasks, killing stale chats, being cautious with MCP servers), and adopting spec-driven development (SDD) to give agents clear requirements, architecture decisions, and tasks. He counters common fears — AI replacing developers, AI code being inferior, learning to code being pointless — using the Jevons Paradox and Dunning-Kruger effect. The talk argues developers must evolve toward systems thinking, ethics awareness, problem formulation, and collaboration rather than pure coding, and that junior developers remain essential.
