Could a drone replace baristas in the future?

IBM has filed a patent for coffee delivery drones that can predict when you need a drink.

The coffee drone would be able to fly around public spaces and deliver cups of coffee to people who need it the most as this clever little drone will be able to predict who need a caffeine pick-me-up!

According to paperwork the drone could be used in any public place where a preordered cup of coffee would be delivered to the drinker. Also if you're thirsty you'd also be able to would flag it down.

The drone will work on face-or voice-recognition software and an electronic ID tag or Bluetooth from a person's smartphone will ensure that the correct cup of coffee gets delivered right to your table! 

We think that baristas are safe in their jobs for now as a drone can't make coffee, can it?
