When I talk to people about artificial intelligence, or AI, they’re often optimistic about how they think AI will improve their lives in the future. What they aren’t thinking about is sweaters. Specifically, how based on previous online behaviors an e-tailer knows that you’re in the market for a warm, blue sweater instead of a long-sleeved gray shirt. Historically, businesses required human interaction in order to understand exactly what a customer needed. Today, that’s no longer the case. Thanks to lots of data and AI, companies now know exactly what you want, when you want it and how you want it.
