阿偉投身行銷產業已有多年，他目前正在瞭解機器學習對行銷人和目標使用者有何幫助。請問他的主要職責會因機器學習產生什麼變化？

Machine learning automates many routine and data-intensive tasks in marketing, such as bidding, targeting, and ad optimization. This automation frees up marketers like A-Wei from manual execution, allowing them to dedicate more time to higher-level strategic thinking, analyzing insights, developing creative campaigns, and focusing on improving the overall customer experience. While machine learning can provide insights into account structures used by similar businesses, it doesn't primarily help in understanding them. It also doesn't automatically convert client briefs into complete account structures; human input and strategic decisions are still crucial. Lastly, while machine learning can improve ad relevance and delivery speed, it doesn't directly enable faster communication with clients in the sense of personal interaction; rather, it optimizes the communication to clients through ads.
