In his Sequoia AI Ascent 2026 fireside chat, Karpathy outlined the Software 3.0 paradigm — programming through prompts and context windows rather than explicit code. He pinpointed December 2025 as the inflection point where 'generated chunks got larger, more coherent, and more reliable,' shifting the unit of programming from writing lines to delegating macro actions. His verifiability thesis explains why coding improves faster than creative work: traditional software automates what you can specify; LLMs automate what you can verify. Key quote: 'You can outsource your thinking, but you can't outsource your understanding.'
