Folks, check this video out. It's one of the better things I've seen in recent months.
Starts off as a bit of a biography, but the Q&A runs through to some great advice on family and what matters in life, credit and managing it, why passwords aren't great (and his interesting assertion that better tech is the answer...*) and then ends with the dangers of IoT and why the more cautious of us aren't being paranoid. (Finally! Justification by a law official that it's not just tin-foil. See last 5 minutes for that)
* any tech has a shelf life and if I've understood correctly this makes a bit of a titanic claim that it's good-as infallible - and that seems to e because the guy hasn't found a weakness in it. And it, therefore, via a device becomes the defacto proof of who you are. For everything. Setting aside big-brother arguments isn't that a crazy assertion that it's the answer? Eggs in one basket, everything has an iceberg etc etc
