But I want my house to listen and sense me. The advantages far outweigh worries. Besides what makes Big Brother isn't the existence of surveillance it is the lack of control over it, who uses it, and how. So fight for open source, transparency, end of advertising/marketing. Not against technology.

I want my house to know what room I'm in (for lights, environment, music following, to adjust temperture when I'm active or too hot, to answer alexa like queries, to announce alarms reminders, to tell me the kitchen is hot and smokey cause I forgot beans on stove, to give me alert someone pulled into my drive, stopped in front of my house, to call 911 if my heart stops.
