Personal assistants are ushering in the age of AI at home

Google Home is the latest embodiment of a virtual assistant. The voice-activated speaker can help you make a dinner reservation, remind you to catch your flight, fire up your favorite playlist and even translate words for you on the fly. While the voice interface is expected to make quotidian tasks easier, it also gives the company unprecedented access to human patterns and preferences that are crucial to the next phase of artificial intelligence. Comparing an AI agent to a personal assistant, as most companies have been doing of late, makes for a powerful metaphor. It is one that is indicative of the human capabilities that most major technology companies want their disembodied helpers to adopt.
