Don't treat AI as a "cyborg" that automates your job. Instead, view it as a "centaur"—a hybrid where the human provides judgment and the AI provides speed and scale. AI handles the grunt work (data analysis, research), while the human makes the final, accountable decisions.

AI models will quickly automate the majority of expert work, but they will struggle with the final, most complex 25%. For a long time, human expertise will be essential for this 'last mile,' making it the ultimate bottleneck and source of economic value.

Despite hype, true 'autonomous marketing' is not imminent. AI excels at automating the first 80-90% of a workflow, but the final, most complex steps involving anomalies, nuance, and judgment still require a human. This 'last mile' problem ensures AI's role will be augmentation, not replacement.

Product managers should leverage AI to get 80% of the way on tasks like competitive analysis, but must apply their own intellect for the final 20%. Fully abdicating responsibility to AI can lead to factual errors and hallucinations that, if used to build a product, result in costly rework and strategic missteps.

Despite AI's capabilities, it lacks the full context necessary for nuanced business decisions. The most valuable work happens when people with diverse perspectives convene to solve problems, leveraging a collective understanding that AI cannot access. Technology should augment this, not replace it.

AI can generate hundreds of statistically novel ideas in seconds, but they lack context and feasibility. The bottleneck isn't a lack of ideas, but a lack of *good* ideas. Humans excel at filtering this volume through the lens of experience and strategic value, steering raw output toward a genuinely useful solution.

Even powerful AI tools don't produce a final, polished product. This "last mile" problem creates an opportunity for humans who master AI tools and then refine, integrate, and complete the work. These "finisher" roles are indispensable as there is no single AI solution to rule them all.

For founders, AI tools are excellent for quickly building an MVP to validate an idea and acquire the first few customers—the hardest step. However, these tools are not yet equipped for the large-scale, big-picture thinking and edge-case handling required to scale a product from 100 to a million users. That stage still requires human expertise.

AI excels at intermediate process steps but requires human guidance at the beginning (setting goals) and validation at the end. This 'middle-to-middle' function makes AI a powerful tool for augmenting human productivity, not a wholesale replacement for end-to-end human-led work.
