Amazon Alexa auto pilot.
Amazon launched a new service in the US a few days ago where your Alexa devices learns from your habits and routines and starts acting for you.
The best example to explain this would be; you have gone to bed and you forgot to turn off some lights, Alexa will then either ask you if you want the lights off or just automatically turn them off, and all this is based on the habits and data Alexa collected based on your previous interactions.
Scary?! it shouldn’t be, you should have been aware that Amazon has been collecting all this data since you started using the products. there are setting to turn all of this off, but I honestly am thankful for all these added features where they put your data to use for useful solution.
