"That's an Echo Chamber" — Self-Diagnosing Myself After Going All-In on AI-Driven Development

I told an engineer at another company that I had gone all-in on AI-driven development, and they answered, "That's an echo chamber." What is an echo chamber, really?

Full remote work is comfortable. But what if a mental-health cost is quietly accumulating behind that comfort?
