So as amazing as these devices are, the trend is to give everything an online component. I think at this point it may be time for a risk/reward analysis first. One, I'm skeptical that these devices even can be secured at this point. In brief you can look at who is being hacked - JP Morgan Chase, the Government, and high level hackers themselves (Hacking Team, probably a lot more less publicized). So what this says is that money, power, and those well versed in the art of hacking - can't stop hackers. JP Morgan spends 500 million a year on security and that still wasn't enough. JC how much would be, a trillion? CS majors love to toss around authoritative sounding jargon, but we've heard that before and watched their designs fail time and time again. SSL, what enabled the secure in https, the backbone of secure e-commerce, thought to be safe for years, bam Heartbleed bug. At this point they do not deserve the benefit of the doubt that they even can secure these devices and so the question becomes what are the implications if they can't? The reward - these devices are absolutely amazing and can solve just about any problem out there with creative developers given enough time and money. The cons - they can't secure these devices and the potential for misuse is also potentially just restricted by creativity. The kicker for the cons, that should give a lot of concern is the force multiplier, a small team can cause a shitstorm, like the SONY hack and the Ashley Madison scandal and in theory just 1 hacker could cause all of that. Nobody wants to be at the whims of the hacker or hacktivist (with this line blurring into terrorist), but that looks to be the current trending direction... http://www.dailydot.com/crime/new-york-magazine-ddos-bill-cosby-cover/ For one thing, I'm of the opinion that certain things should not have an online component. If the trend is for all cars to have onboard wifi, I don't like that and I think the consumer should have a choice. They didn't fix the current wifi security vulnerability they slapped a band-aid (patch) on it. In the audit model of security where they react to zero days, this is a horrible idea if all cars are online. It could take months to find a band-aid. And with more and more people becoming computer savvy, Jihadi John is a CS major btw, combine this with a typical force multiplier effect, and this looks like a risky trend.
