I think the translation from human speech to something a computer can execute already qualifies as AI. But there are a lot of other things that need to be considered, if the AI aims to be the equivalent of a human assistant. It needs to determine how much snow requires a snow blower (a smart AI wouldn't buy for a couple of snow flakes), to guess what model of snow blower the user would want (which may involve checking the users' finances, brand preferences and it may ask how much space is available in the garage) and to determine what else needs to be checked, like vacations. It would also need to figure out the right time to order, because it should arrive before it is needed.
