In this episode of the Elixir Mentor Podcast, I chat with returning guest Daniel Bergholz about leveraging AI tools like Windsurf and Claude to dramatically improve Elixir development workflows. Daniel shares his journey from skepticism to becoming a power user, demonstrating how these tools can help developers build faster without compromising quality.

Daniel walks us through his practical approach to incorporating AI into both professional development work and side projects. He explains how to effectively use features like rules files, web documentation integration, and memory systems to get the best results when generating Elixir code. The conversation covers important nuances about how different programming languages perform with AI tools, with Daniel noting that while JavaScript/TypeScript might get near-perfect results, Elixir requires more guidance but still provides excellent value.

The discussion takes a critical look at the "Vibe coding" trend (generating code without understanding it) and offers a more responsible alternative that we call the "sniper approach" - using AI with precision and knowledge. We explore how AI tools are changing developer roles, potentially transitioning programmers from pure coders to more holistic product engineers who can focus on customer needs while leveraging AI for implementation.

Whether you're an Elixir enthusiast curious about productivity tools or a developer interested in responsible AI usage, this episode provides practical insights on balancing automation with craftsmanship. Daniel's experience demonstrates that AI can be a powerful assistant when used thoughtfully, helping developers produce higher quality work in less time.
