I'm not saying they are a good thing per se, just a reassuring thing. It means we still need to be in control of our systems, and can't blindly let our systems control us, because indeed they are fallible. It's of course rather philosophical. There's also a big difference between these sort of vulnerabilities, and the sort of problems that enable for example ransomware, which is a serious issue that has a more difficult solution than simply designing more robust hardware. Anyway, if you're intrigued maybe check out Ghost in the Shell sometime (not the one with Scarlett Johansson, although it is enjoyable, it's not really the same thing), if it needs to be Hollywood, then maybe the Hackers movie would also work a bit (with Angelina Jolie).
