Defining AI and Its Applications in Health Care

Have you ever asked Alexa to play your favorite song, call for a ride, or adjust your home’s temperature? Does your car alert you when you drift out of your lane, automatically slow down to maintain a safe distance, or even park itself? Have you noticed how Amazon suggests products that seem almost too perfect for your needs? These are just a few examples of how artificial intelligence (AI) is seamlessly integrating into our daily routines subtly yet profoundly altering how we live.

AI is not just the latest in a series of technological revolutions—it is poised to be as transformative as the personal computer, the Internet, and the smartphone. If you pause to reflect on how dependent you are on these technologies today, it becomes clear that AI will embed itself into our lives in a similar, irreversible way over the coming decade.

But what exactly is AI? Formally, AI is defined as the study and design of intelligent agents—computer systems that perceive their environment and take actions to maximize their chances of success. These actions could range from parking a car within the lines to predicting equipment failures or accurately interpreting a radiology image. AI’s capabilities span a broad spectrum, including voice recognition, contextually aware interactions, pattern identification, and complex process automation. Whether it’s a recommendation engine suggesting holiday gifts or an AI system extracting information to create accurate bills, AI is becoming an integral part of the fabric of our daily existence.
