Today, it is understood as a branch of computer science that focuses on creating machines, computer programs, or software systems that can perform tasks typically requiring human intelligence.
More broadly, artificial intelligence refers to a non-human program or model that can solve sophisticated tasks, such as translating text or identifying diseases from radiologic images.
The field encompasses various approaches to creating intelligent behavior in machines, from rule-based systems to sophisticated neural networks that can learn and adapt.
The scope of AI has expanded significantly since its inception, now encompassing everything from simple automation to complex systems that can engage in creative tasks, strategic planning, and even scientific discovery.
Modern AI systems demonstrate capabilities that were once thought to be uniquely human, including pattern recognition, language understanding, decision-making under uncertainty, and learning from experience.
