Amazon alien technologies

My friend gave me an echo dot and a fire tv stick today as a gift.

It took a couple hours to set up and the stuff works really good but it's freaky.

You can ask it some really off the wall questions and it knows all the answers.
It can turn the lights on and off, open the garage door, turn on the coffee maker.

It's really nice but it's freakish......

Anyone on here use this kind of thing and know more things it can do?
