Can you hear Alexa now? 

Amazon's smart assistant was the talk of the town at Europe's biggest tech trade show.

We take a look at what Alexa's dominance means for the Google Assistant and Apple's unreleased HomePod. 

Also on today's podcast, we talk about how artificial intelligence is protecting Las Vegas from cyberattacks, and Elon Musk's warning about AI starting World War III
