AI cannot replace the role of a Chief Marketing Officer in cash-strapped startups, as it lacks the human judgment, intuition, and political skills essential for effective marketing leadership. Instead, AI should be viewed as a tool that can enhance the CMO's effectiveness by automating tactical tasks, allowing them to focus on strategy and creativity. The fractional CMO model is proposed as a viable solution for startups needing expert guidance without the financial burden of a full-time hire.
