My security is simply not keeping anything important on my computer/phone so if anything goes wrong, it ain't no thing to just wipe the drives and start over from scratch.

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.

I have no home automation stuff. My tech at home is a

Dd-wrt on the router.

The only real techy thing I have is a pihole running a raspberry pi. Other than that my house is dumb. I despise my smart tvs because I can't control them (webos).
