Yes ... our lives will get a lot more "interesting" as the script kiddies figure out how to disrupt physical infrastructure. Most of the state actors aren't interested in crashing these systems (at least for now - that could change with the appropriate war). Instead, there's a profit motive in electronic espionage. When this knowledge is acquired by those that just want to break things, we'll find life a bit harder.
I do think a lot of the "comfort" that we have now is security through obscurity, i.e. lack of motive or passion. Ignoring the discussion of who actually was behind the targeting of the Clinton campaign, it's clear that all it took to make a massive impact is a batch script and very limited social engineering: http://motherboard.vice.com/read/how-hackers-broke-into-john...
That reminds me of another point ... we're getting used to seeing breaches that expose personal data, credentials, etc. But what other kinds of "data disasters" might come about through mass breaches similar to the MongoDB story on the front page yesterday. It seems inevitable that there will be confidential and/or proprietary data in some of these breaches that won't lead to identity theft but will lead to embarrassment or have financial ramifications.
