Artificial intelligence is the theory and development of computer systems able to perform tasks normally requiring human intelligence, such as visual perception and speech recognition. John McCarthy first coined the term in 1956 at the first academic conference on the subject. AI has since been applied to mobile phones, gaming, voice recognition, robotics, and other areas. Deep learning is a major focus of AI research at companies like Google. While AI shows promise for automating jobs and improving lives, it also presents risks if not developed responsibly, as machines currently lack human attributes like emotions and ethics. Both pros and cons of AI must be considered for its full impact and development.
