AI refers to computational tools that can perform certain tasks in place of human intelligence. Technology is advancing at a breakneck speed, much like the exponential growth experienced by database technology in the late twentieth century. As a result, databases have evolved into the core infrastructure for enterprise-level software. In a similar fashion, most of the new value-added in software over the coming decades is expected to come from AI, at least in part. AI is used everywhere, from the modern smart phones to advanced quantum computers. Hence, in this day and age, it's crucial that you understand the basics, if not advanced, of the concepts involved in artificial intelligence.
