What About Rails? (jardo.dev)

At Rails World 2026, David Heinemeier Hansson (DHH) delivered a keynote that sparked discussions in the AI/ML community by announcing his shift from traditional programming to a model centered on Large Language Models (LLMs). DHH claims that hand-coding may soon become economically unfeasible, marking a significant pivot in how developers might approach software creation. He emphasized LLMs’ role in generating code, stating that they can achieve outputs he previously took months to write, suggesting a new era where reading code becomes the exception rather than the norm. This aligns with his company's strategy shift to using Rust for backend development while leveraging LLMs to create more efficient applications, departing from the traditional Ruby on Rails framework. This transformation raises essential questions about the future of Rails and the developer community. While Hansson still recognizes Rails as a valuable tool for web applications, his admission that only 3% of his recent output was in Ruby—contrasting sharply with past practices—signals a possible decline in the framework’s relevance. The increasing reliance on LLMs and the call for every service to provide Command Line Interfaces (CLIs) highlight a growing trend towards automation and simplified interactions with technology. As many programmers begin to adapt to this shift, DHH’s vision could represent a pivotal moment, urging the AI/ML community to reconcile these changes with the traditional roles and skills of developers.
