Should AI agents decide audience selection, personalization, and customer journeys?

Audience selection. Journey orchestration. Channel optimization. Personalization. For years, marketers have manually controlled these decisions through rules, segments, and workflows. But as AI agents become more capable, I wonder if we're moving toward a model where marketers define the goal and agents handle the execution. Instead of deciding who gets what message and through which channel, could AI agents continuously optimize those decisions based on customer behavior and business outcomes? Do you see marketing as a strong use case for AI agents, or are there too many brand and customer experience considerations to hand over that level of control?
