What two things are marketers realising as machine learning becomes more widely used? (Choose two)

As machine learning becomes more prevalent in advertising, marketers are realizing its true nature and requirements. Automated campaigns, while powerful, are not set-it-and-forget-it solutions; they require human guidance, strategic input, and intelligence to define goals, interpret results, and optimize effectively. This means that expertise in understanding and working with machine learning and automated systems is becoming increasingly valuable, as marketers need to know how to leverage these tools to achieve their objectives. Machine learning primarily optimizes campaign performance, not directly builds client relationships. Automated campaigns excel at data processing and optimization, but human creativity remains essential for compelling ad copy and visuals.
