It is certainly frightening that some can hack into the vulnerabilities of things like passenger aircraft. That being said, I am glad that these vulnerabilities were exposed before they were used in malice. I'd much rather have cyber security and national security experts hack into these systems to expose their vulnerabilities than terrorists and criminals.
As for the prospect of lawyers in this regard, I'm not so sure I can agree. As someone in the law field, I can say there has been plenty of things to keep lawyers busy for centuries just involving human interactions. In fact, there is an entire field of law to deal with human-caused mishaps and wrongdoings onto others, whether deliberate or not, in civil (think $) court. It's called torts, but most will know these types of lawyers as "ambulance-chasers". Oh, and these lawyers make a good deal of money due to human error and human stupidity.
Let's also not forget the attorneys that represent their clients in DUI cases. Thousands pick up clients each day given our national average of 1,500,000 DUI cases a year. I can't imagine these attorneys are too optimistic about automated driving in the future for their field of practice. In essence, many lawyers exist due to flaws with humans whether it be deliberate, out of negligence, or even purely accidental. I can't see machines as being as juicy of clients, especially after the technology inevitably matures.
If anything to me, the progress of technology and its interconnections come as annoyances more than risks. Companies and people want your info, want you to like this, follow this, share this, download that, tag you, and generally spam you. Ads are everywhere and often generated for you based on your searches and interests as they've tracked your internet activity. It's the cost of "free". Many websites are free to use, most email accounts are free to use, there are countless free apps, etc. What they are not free from are the ads, tracking, and spam.
And now, in their infinite wisdom, some politicians want to hand over the reigns of the internet to private corporate entities.
