Problem is most mechanical locks aren't very good either. See lock picking lawyer on YouTube. Plus, the weakest link in electronic infrastructure is often physical. I can't find it right now, but there are some pretty amusing red team videos on YouTube of various physical vulnerabilities. I think people know more about the shortcomings of their particular area, so are more likely to use the things they don't specialize in.

Yep, completely true for me at least. I have a colleague who has everything smart though, so it's certainly not everyone, but I keep my house intentionally as dumb as possible. The only household thing I have that is "smart" is my robot vacuum, but we hardly ever use it anymore because doing it with a good old fashioned vacuum cleaner is so much quicker.

Edit: I do have a smart tv as well, actually, but with google assistant and the microphone disabled.

I was so confused at first with the mechanical windows... (i thought they where talking about the OS)

My wife and I don't use smartphones but use alexa devices. Im not sure at what point convenience wins over the privacy I would want. Wish I had more time to work out better solutions. Sorta funny that in general younger folk tend to accept more than older given that older folk have less to lose. I mean the closer death is the less you need to worry much about what they are going to get off you.
