Having just watched the Joe Lycett programme, Got Your Back, I would want to have as little "smart" technology in my home as possible.
The programme showed how easy it is for an unscrupulous person to hack into all the technology in a person's home - cameras, TV, voice activated assistants such as Alexa and Siri, lighting, sound and heating systems, etc, etc., to disable them or to invade people's privacy either for entertainment or for criminal purposes. There have been several instances where Alexa has either been hacked or has incorrectly responded to a verbal cue:

" Last year, an Amazon customer in Germany was mistakenly sent about 1,700 audio files from someone else’s Echo, providing enough information to name and locate the unfortunate user and his girlfriend. (Amazon attributed this “unfortunate mishap” to human error.)
"In San Francisco, Shawn Kinnear claimed that his Echo activated itself and said cheerfully: “Every time I close my eyes, all I see is people dying.”
"In Portland, Oregon, a woman discovered that her Echo had taken it upon itself to send recordings of private conversations to one of her husband’s employees. In a statement, Amazon said that the Echo must have misheard the wake word, misheard a request to send a message, misheard a name in its contacts list and then misheard a confirmation to send the message, all during a conversation about hardwood floors. Not great, Alexa."
