An older article, and specifically about their Super Bowl ads, but a fascinating answer to a question I had directly from the source at Amazon.
(Speaking of being intrusive, lately Alexa has also been very aggressive about promoting other Alexa capabilities to the point that my kids asked me to fire her. It's looking like Siri + Homebridge will allow me to do that.)
I was wondering it that was just me, it seems a lot of responses are now ending with "...by the way, did you know i can...". I sometimes listen to NPR ( please don't judge ) and i get the "...we still don't have your zip code..." a lot but i think that is an NPR thing and not an Alexa thing.
Alexa will then reply, "I will snooze my suggestions…for now." (The foreboding pause was implied.)
