"If you sell the tool, you're in a race against the model. But if you sell the work, every improvement in the model makes your service faster, cheaper, and harder to compete with. A company might spend $10K a year for QuickBooks and $120K on an accountant to close the books. The next legendary company will just close the books."
"Writing code is mostly intelligence. Knowing what to build next is judgement. Translating a spec into code, testing, debugging: the rules are complex but they are rules. Judgement is different. It requires experience and taste, instinct built on years of practice."
"A copilot sells the tool. An autopilot sells the work. Until recently, AI models were still developing intelligence and judgement, so the right approach was to build a copilot first: put AI in the hands of a professional and let them decide what to do with it."
The most successful AI companies will shift from selling tools to selling the work itself. As AI models become more capable, tool-based businesses face the risk of becoming features in larger models. However, service-based businesses benefit from model improvements, which make their offerings faster, cheaper, and more competitive. Software engineering demonstrates this principle: AI now handles most intelligence work autonomously, leaving judgment to humans. This pattern will extend across all professions. The distinction between copilots (selling tools to professionals) and autopilots (selling completed work) represents a fundamental business model shift. Companies that position themselves as service providers leveraging AI will outcompete those selling AI tools directly.
