My wife, separated, has a BSc In CompSci and a BA in Maths and she has one. She says she has unclicked all the settings but I'm not sure she knows exactly how it works. She wants it to stream music for her. In which case it is far too well specced for that role but she doesn't want to stream her phone to some speakers for some reason.
It means if I visit I will studiously avoid talking about anything serious including about the state of our non marriage. I'm constantly aware it's there when I visit. I might start saying 'Alexa delete the last five minutes' every five minutes. Hmmm, perhaps that should be the last 6 minutes every 5 minutes. No wriggle room.
