AI is being applied in healthcare, entertainment, finance, and data security. In healthcare, AI can analyze large amounts of medical data to help doctors spot patterns and determine if hospitalization is needed. In entertainment, AI makes recommendations for movies and products on services like Netflix based on users' interests and behaviors. In finance, AI performs fraud detection and uses natural language processing to analyze social media sentiment and provide financial advice. For data security, AI helps identify software vulnerabilities and protects against growing cyber threats.
