Slack Employee #1 Johnny Rodgers & Jimmy Scheinblum: The Limits of AI Engineering and Launching Supernice

In this episode of After Coding, Keith Adams sits down with James Scheinblum (Jamie/Jimmy) and Johnny Rodgers (JR), co-founders of Supernice. JR was Slack's first employee and a founding team member, and Jamie was one of the company's earliest engineers.

We are moving past the era of typing syntax and into the era of managing systems. Jimmy and JR walk through how they have completely abandoned manual coding for a pure agent-driven workflow, explaining why the traditional "first commit" is dead and how a living folder of agent-readable specs serves as their new source of truth.

In this episode, we cover: 
• Leaving Slack to build Supernice with a greenfield, AI-first setup 
• Moving from manual syntax to a "spec-driven" engineering workflow 
• How AI agents eliminate stale tech documentation and tribal knowledge 
• Why LLMs replaced traditional debuggers in daily development 
• The search for software’s "Move 37" and why AI can’t fake product taste 
• Shift in technical careers: Why all roles are collapsing into the "Product Engineer"
