It's the truth behind Amazon Echo!
(Warning: The Geek Factor in this video is set to HIGH)
Also: this is not a review, it's a demonstration to show how the Echo interacts verbally (with a comparison to Siri). There are a lot of very good product reviews of Echo on YouTube, just search for "Amazon Echo Review."
This was made and posted to YouTube back when the Amazon Echo first came out (over 2 years ago), and at the time there was no conspiracy buzz going on about them. The honest and innocent point to the video is that it is a geek toy for scifi fans and that even the creators of it at Amazon openly admit they wanted to "make the computer from Star Trek."
For the people who expected this to be a conspiracy expose, and complain that they wasted 8 minutes of their life watching this video, I hereby magically grant you 8 more minutes of life. You're welcome. :)
