AI is not a future concept; instead, it is a reality being implemented in many industries today. There are several instances when AI is already changing the world and significantly enhancing human skills. Here are a few examples: finance, national security, healthcare, criminal justice, transportation, and smart cities.

Artificial intelligence (AI) algorithms are developed to make decisions, typically utilizing up-to-date data. They are not like passive machines, which can only act mechanically or according to predetermined rules. They combine data from many sources, evaluate it instantly using sensors, digital data, or remote inputs, and then act in accordance with the inferences they make from the data. They can make sophisticated choices because of significant developments in storage technologies, computer power, and analytical techniques.
