That is what the AI said:

1. Classic Coding (Traditional Development) In the classic model, developers are the primary authors of every line.

    Production Volume: A senior developer typically writes between 10,000 and 20,000 lines of code (LOC) per year.
    Workflow: Manual logic construction, syntax memorization, and human-led debugging using tools like VS Code or JetBrains IDEs.
    Focus: Writing the implementation details. Success is measured by the quality and maintainability of the hand-written code.

2. AI-Supported Coding (The Modern Workflow) AI tools like GitHub Copilot and Cursor act as a "pair programmer," shifting the human role to a reviewer and architect.

    Production Volume: Developers using full AI integration have seen a 14x increase in code output (e.g., from ~24k lines to over 810k lines in a single year).
    Work Distribution: Major tech leaders like AWS report that AI now generates up to 75% of their production code.
    The New Bottleneck: Developers now spend roughly 70% of their time reviewing AI-generated code rather than writing it.

I think realistic 5x to 10x is possible. 50.000 - 200.000 LOC per YEAR !!!! Would it be good code? We will see.
