Thanks, that's good know. I'll look into it but I'm not a fan of home assistance either even though everyone tells me our house would be awesome with it....sigh...
I feel like an old man because of this though. haha I can see the benefits of a smart home and I know our home would be even better because of it but man the privacy issues alone make me very hesitant about making the transition from a dumb home to a smart home....
I can tell you this: I've been a high level IT engineer for 30 years. I've also used all of Google's services since their introduction (even worked on their beta products). I have smart speakers and smart devices all through my home. Never once in my 15+ years of using these devices/services have I had any kind of breech, privacy violation, or anything that made me feel uncomfortable.
These services are free, and to fund them the data (which is mostly anonymous) must be monetized. Everyone wants their own personal R2-D2, and that's what Google Assistant is to me. I have tracking turned on on my phone that lets me track client visits via Google Timeline to keep my timesheets straight. This tracking also automates things like heat/air conditioning when I get near my house, can trigger music or lights, and other things. Smart speakers allow me to have whole-house music that plays the same thing on all speakers. In the morning I get a gentle alarm that then reads off my schedule, traffic to work, and any news stories I've been interested in based on my browser history.
I have smart lights, smart TV's, Google WiFi, cleaning robots, Nest thermostats and smoke detectors, smart screens, and smart appliances. My family loves them and they're incredibly convenient. In exchange, I get targeted ads in Gmail and banner ads on websites. That's about it. I've had no other bad experiences. Most people that have had weird security breaches had to do with weak passwords. I highly recommend turning on 2FA for ALL of your cloud services to keep yourself safe.
