I used to joke about being uncomfortable with people visiting my apartment carrying smartphones, now I'm actually becoming uncomfortable with people visiting my apartment carrying smartphones. All of my technology is dumb as shit/rooted. I've physically taken the webcam out of my new laptops for years before the first power up, which is with a Debian DVD.

Anybody practiced and willing to put in a few hours of work could own me. I could own me, so I know it's true. People who aren't technical with software, hardware, and web architecture just have no chance.
