Artificial intelligence (AI) is a branch of computer science that aims to create intelligent machines. AI works by machines learning from their surroundings and thinking for themselves, similar to how humans learn. AI is being used in many applications in daily life from automated financial investing and social media monitoring to smart assistants, manufacturing robots, and proactive healthcare management. Robots can perform tasks through machine language, which is part of AI, with the help of humans. While AI has advantages like low error rates, ability to work 24/7, and use in dangerous tasks, its development has high costs and there are concerns it could significantly increase unemployment by replacing humans.
