Thought vending machines had reached the height of efficiency? Japan respectfully disagrees. New drink-dispensing machines in Asia use a camera to guess your age and gender, factor in the weather conditions, and then recommend you a product based its findings. The questionable accuracy and political correctness of this method aside, why do we need this? Is it honestly that difficult to decide what to get from a vending machine? Does the problem of indecisive vending machine patrons really require a solution? This seems to us like a waste of technology and money. source
