Ricardo got an Amazon Echo for his birthday and he loves it. He's wondering how smart it can get, though. Leo says it can play music, get the weather, and hundreds of other information gathering techniques based on Echo "recipes." It's getting smarter. Artificial intelligence, thanks to machine learning, is growing by leaps and bounds, except for Siri on the Apple platform. Siri is actually getting dumber because Apple values privacy more than gathering the data needed to make it smarter.
The Echo has multiple microphones in order to hear you anywhere in the house when using the trigger word "Hey Echo." It then sends that data to Amazon to analyze and process the request.
