GitHub argues the cost of writing code dropped but the cost of owning it didn't
GitHub Blog·high signal
GitHub's engineering blog published a framework for deciding which changes are actually cheap in the AI era, arguing that generation cost collapsed while maintenance, review, and ownership cost stayed flat. The piece is a direct rebuttal to the assumption that cheaper code generation means teams should say yes to more work. For a solo builder shipping with agents, it is the clearest articulation yet of why agent throughput does not translate into shippable scope.
