Ed, I’m new to Medium, and it’s taken me this long to figure out how to reply to your comment — sorry for the delay, and thank you for your question. Professionally, I provide consulting on cybersecurity. Some of my clients are public utilities, and they have a lot of automated systems. Now, the same threats they face — in the four categories shown in my article — are starting to be faced by the general public, as we automate our homes and connect them to the Internet. So, I sleep fine; but people need to be educated about these things. All the best to you.
