Startups are exploiting AI's hazy definition to cash in on the hype

What exactly is artificial intelligence? In much the same way that you'd be a bit stumped if someone demanded that you provide a hard and fast definition of say, philosophy, there isn't a satisfactorily rigorous answer to this question. As the Stanford Encyclopaedia explains, AI's definition falls under the category of "remarkably difficult, maybe even eternally unanswerable, questions, especially if the target is a consensus definition". But that hasn't stopped startups from jumping on the buzzword bandwagon. To get around this problem, most AI definitions settle for a muddled approach.
