Based only on the title, this appears to be an opinion or commentary article about the renewed reputation of “lines of code” as a software metric. It likely argues that the concept has not necessarily changed, but the way people talk about it has. Without the article body, no specific claims, examples, AI tools, or conclusions can be confirmed.
The author argues that LLMs are eroding three pillars of his software engineering career: domain knowledge, debugging skill, and architecture judgment. Tools like ChatGPT, Claude, Claude Code, Codex, MCP, Sentry MCP, and DataDog MCP increasingly handle design, implementation, and difficult production bugs. The essay frames this as a labor-market concern, not just a tooling debate: if expertise becomes promptable, engineers may struggle to remain differentiated.
