At some stage in the not-so-distant future, I predict that AI will become smarter, and be able to accurately predict actions before they happen. Like a creepy sci-fi movie (anyone seen Minority Report?), I foresee super-smart algorithms being able to analyse your actions, then with a close degree of accuracy, predict your next move.
It already exists in a small way with e-commerce abandon cart emails. A store predicts, or hopes, that by adding a product to cart then leaving, your intention was to purchase the item, you just got distracted or needed a nudge. In a similar but more complex way, these same systems will monitor your every move, or series of movements, then predict your intentions, allowing them to serve up real-time offers and responses.
