The post covers the language's features (vectorized operators, prototypal inheritance, mark-and-sweep GC), the methodology behind the experiment, and four key skills for agentic engineering: problem selection, communicating intent via spec documents, creating a rich agent environment (test suites, sanitizers, linters, Docker with full permissions), and optimizing the agentic loop. The author reflects on authorship and credit, mental health risks of addictive AI tooling, and concludes that software engineering skills remain essential but will transform significantly. ## Full article daily.dev links to this article rather than hosting it.
