AI
1. An abbreviation for "artificial intelligence," the ability of a computer to perform functions thought to require intelligence or some form of decision making. AI will change the way just about everything works—in ways we haven't yet imagined.
2. An abbreviation for "as if," an interjection indicating complete dismissal of what has been said or suggested, implying that it is not the case or would never happen. AI! There's no way I'm staying home on a Saturday night!
