Just thought I'd share that I moved into a new house last weekend and one thing I discovered is that the crazy person who lived here before me had Cat8 ethernet wired to every room in the house. I don't know why anyone would ever do that, but the good news is it will only take 5 seconds to reinstall Civ6 after I uninstall it in disgust, which happens on a weekly basis.
I used to work somewhere which, among other things, did security systems and in-home networking. We had a customer who was a typical small business tyrant, except his business was run out of his house. Oh, and he was extremely paranoid, even more so than these dudes usually are. He had every inch of his house, inside and out, covered with cameras and would call us the second any of them so much as blinked out for a second.
But yeah, he had a setup like this apparently. I never figured out what he did other than monitor his cameras. We speculated the real issue was he didn't trust his wife as he was away on business often, leaving her at home in the Truman Show. We didn't set this up for him. He'd burnt through two other IT companies by the time he got to us. And yes, after a while (too long, if you ask me) he was requested to find someone else to service his IT needs. Luckily, I only had to deal with the guy on the phone but my co-workers had to make the trip out there. I guess his network would have rivaled office buildings we'd worked on. lol
