Agentic Cookies Will Change Digital Privacy and Personalization
In this editorial, Luis Fernandez, a tech executive at VML, introduces the concept of 'agentic cookies'—AI-powered browser cookies that act as personal data assistants. Unlike traditional cookies, these would use edge AI models like WebLLM to learn user preferences and negotiate data sharing with websites in real time. The article traces cookies back to Netscape in 1994 and predicts they will evolve from passive text files to active, privacy-aware assistants. Marketers would gain access to more accurate zero-party data with less tracking, while users would retain control over their information. The author argues this shift could replace cookie-consent banners and potentially disrupt the traditional AdTech ecosystem.
