Google will soon check your age using machine learning technology, coming first in the US. The AI-based age checker will work alongside Google's SafeSearch Filter, sensitive ad content restrictions, YouTube and Play Store's age-restricted content, and other safeguards that use AI. According to Google, users who are under 18, the age of legality in the United States, will have to undergo a process powered by machine learning to determine their age and avoid getting access to inappropriate content or services.
