> Do we also have nightmares about a hacker stealing a government's back door key and giving us a heart attack in our sleep?

While hackers interfering with embedded devices in people is worrying I'd be more frightened about bugs in the devices from sloppy minimum cost systems.

While not awesome current stuff is ok(ish) largely because it's a relatively small market so the people in it are better than the average dev.

I've been programming a long time, I'm a reasonably talented developer and I wouldn't touch that stuff at all.
