Summary:
- Google is developing an AI system that can estimate a person's age based on their search history and online activity.
- This technology could be used to better target ads and content to users, but it also raises privacy concerns about how much personal information tech companies can gather about individuals.
- Experts warn that this type of AI-powered age guessing could be inaccurate and lead to discrimination, so it's important for companies to be transparent about how they use these technologies.
