Echo/Google Home infinite loop - YouTube. I have both an Echo Dot and a Google Home device on my desk in my office. No, I don't need both; but, I do review this stuff on the blog. So, I was intrigued by this YouTube video, in which a user got the two devices talking to each other in an infinite loop. In fact, while I was playing the video, the use of the Alexa catchword set off the Echo Dot in my home office. Talk about the invasion of the speaking bots. I wonder what would happen if you got an army of these devices all talking to each other simultaneously. I smell a new hit song for Xmas.
