> On a side note, do these devices only capture human audible range of signals?
I wonder about this one. Everyone's device has the same "password" (i.e. "wake word"), the device is attached to your home network and associated with your credit card, and programmatic ads apparently receive little to no vetting. Even if there are no bugs in the code that sends the audio to Google/Amazon and deals with the results, I'm reminded of an article here awhile back about researchers creating special eyeglass frames to make one face look like a completely different one to modern zillion-parameter facial recognition algorithms. This will not end well.
