Why anti-vibe-coding
Stay in control of your codebase.
Most AI courses teach you to say "yes" faster - accept the AI's output, ship it, repeat.
Bruce teaches the opposite: structured oversight that keeps you in control of your codebase. The Ask → Plan → Agent framework prevents the "yes loop" that turns AI assistants into a crutch.
If you've been on the fence about AI in Elixir - especially in production systems - this is the teaching that connects the dots.
"I don't want you to write Elixir faster with AI. I want you to write better Elixir, with AI, without losing what makes your codebase yours."
About Bruce Tate
Bruce is the author of more than ten programming books, including Seven Languages in Seven Weeks, Programming Phoenix, and Designing Elixir Systems with OTP. He's trained thousands of developers and currently writes the Stop Vibe Coding blog series and The AI Crises Series on engineering and AI.
Most students cite Bruce's teaching style - clear mental models, real metaphors, no slides - as the reason they stay.
