There are much worse things:

1) imagine internet connected ovens all with a virus that puts them into
self cleaning mode (e.g. get as hot as you can) on Xmas day, thus
literally millions of dinners/etc getting burnt and stinking up the house

2) Imagine a network connected kettle that has a software safety to
prevent overheat... the attacker tells it to get as hot as possible
until it melts/catches fire. My boss has such a kettle, luckily the
overhead is "in hardware" apparently...

3) Imagine your dishwasher full of heated steam under pressure telling
you it's ok to be opened... you get a face full of steam and burned

4) your Internet connected smoke alarm, which can receive software
updates automatically (e.g. the NEST protect now owned by Google) is
programmed to not alert on fires between say midnight and 8am while
you're sleeping.. and your kettle is catching fire.

5) self driving cars - existing car software is terrible (like all

6) all the internet connected medical devices, from Dave Dittrich's
slides in 2003 (can't find an older copy):

We've already crossed the bridge of software flaws being able to kill
people, luckily there's not much economic incentive for the bad guys to
exploit them ... yet. Would you pay 2 bitcoins to unbrick your car?
