Artificial intelligence is getting more powerful, and it's about to be everywhere

There wasn't any one big product announcement at Google I/O keynote on Wednesday, the annual event when thousands of programmers meet to learn about Google's software platforms. Instead, it was a steady trickle of incremental improvements across Google's product portfolio. And almost all of the improvements were driven by breakthroughs in artificial intelligence -- the software's growing ability to understand complex nuances of the world around it. Companies have been hyping artificial intelligence for so long -- and often delivering such mediocre results -- that it's easy to tune it out. AI is also easy to underestimate because it's often used to add value to existing products rather than creating new ones.
