Always tweeting Tesla ( TSLA) CEO Elon Musk doesn't seem too scared of North Korean nuclear missiles striking his U.S. based Gigafactory. 
 
But he is worried about the long-range effects of more powerful computers.
 "If you're not concerned about AI safety, you should be. Vastly more risk than North Korea," Musk tweeted on Friday night. 
 
While Musk's comments seem somewhat bombastic, they do shed light on the growing influence of artificial intelligence on humanity.  
 
From Starbucks ( SBUX) to IBM ( IBM) , the use of artificial intelligence by big companies to alter your behavior is becoming a major thing.
 
The most recent example is coffee giant Starbucks, as TheStreet recently reported.

If you always have a caramel macchiato on Mondays, but Tuesdays call for the straight stuff, a double espresso, then Starbucks is ready to know every nuance of your coffee habit. There will be no coffee secrets between you, if you're a Rewards member, and Starbucks.

This fall as Starbucks rolls out more of its new cloud-based Digital Flywheel program, backed by artificial intelligence (AI), the chain's regulars will find their every java wish ready to be fulfilled and, the food and drink items you haven't yet thought about presented to you as what you're most likely to want next.

So targeted is the technology behind this program that, if the weather is sunny, you'll get a different suggestion than if the day is rainy. Or expect suggestions to vary on the weekend or a holiday, as opposed to a regular workday. If it's your birthday, Starbucks will offer a personalized birthday selection. If you patronize a Starbucks other than you're regular haunt, Starbucks will know that too.
