Build, Adapt, or Get Eaten by AI: Modern Software Engineering in 2025 (w/ Stephen Barr)


Listen Later

When AI is moving this fast, you’ve got three choices: build, adapt, or get eaten.


In this week's Tech Talk with Stephen Barr, we unpack real-world lessons for modern software engineers, where “vibe coding” hits the wall, and the practical guardrails every engineer needs to ship safely in 2025.


You’ll hear wild stories from the field (like that time when a client's API keys were hard-coded in the frontend 🤯), why fundamentals still win, and the exact AI tool stack we use day-to-day to stay ahead.


In this episode, you’ll learn:

  • Why “build + adapt” beats waiting for the next model drop, and what the AWS Hero Summit reinforced about real engineering.

  • A vibe-coding post-mortem: exposed API keys, how it happened from vibe coding, and how to prevent it (even with AI in the loop).

  • “Vibe coding” vs. engineering: backups, PITR, DR, and the boring stuff that saves companies.

  • How deeper fundamentals (Rust/Haskell/typing) make your AI prompts—and outcomes—dramatically better.

  • Our current AI tool kit (Bedrock, OpenRouter, Perplexity, Claude Code, Kiro) and when to use each.
