AI agents change code economics: maybe nobody needs to understand all the code

Genaforvena · reddit · 2026-09-09

An engineer building a production DSP argues agents upend the assumption that code must be understood: code is text that can sit unread, understanding can be reconstructed on demand, and observability of the running system beats code review. He also defends duplication as decoupling — agents excel at changing twenty boring copies — and criticizes app-layer abstractions that merely displace information. His AI-era target: explicit control flow, local state, narrow boundaries, aggressive observability, cheap duplication, few abstractions.
