Google assistant is a live speech interactive Artificial Intelligent service for mobile devices, such as phones, and home devices, those cylindrical things you talk to in your house that seem to be the rage.
Anyway the Google AI is just dam amazing, It can quickly decipher what you are asking and give you fast accurate answers.
You can put money on it, that within a year DJI will be putting out some sort of AI on their software such as the Go app.
Yes, so you will be talking to your drone! Asking it to investigate some elements in the environment reporting on the state of the remaining power and light conditions etc, etc.
