A software developer's personal journal entry reflecting on the rapid and disorienting shift in the software industry caused by LLMs reaching a new capability threshold in late 2025 and early 2026. The author describes witnessing colleagues move from experimentation to full LLM-assisted coding, while simultaneously facing an explosion of security vulnerabilities enabled by the same tools. The post captures the community fracturing over LLM adoption, the arms race between code generation and vulnerability hunting, and the author's own reluctant adaptation. No conclusions are drawn — it's a raw account of living through what the author considers the most significant change to software development in their career.
