Coding agents didn't kill open-source moats, they moved them, argues dev

Marc Schmidt argues that before coding agents, open-source maintainers' moat was being the only one who truly understood the codebase. For simple projects that moat is gone — anyone can now direct an agent to enhance the code without the author.

But he claims the moat has moved, not vanished: complex projects still require tuning a harness across hundreds or thousands of details where the original author holds the edge. Quoted by levelsio, who lists remaining moats: proprietary data, network effects, audience/distribution, physical components, capital, and regulatory barriers.
