That was kind of my point. People have got used to Bluetooth being flaky, WiFi having dead spots, WiFi performance not being that great, etc. They've forgotten how good wired connections are.

In my house I have a nice WiFi set up and performance from the Apple TV was awful. I discovered that someone had put in some Cat 5 in the walls and managed to test it, splice a few cables and get Ethernet working. End of trouble.

I use cable where I can and wireless only when I absolutely have to.

Same here. I specifically wired everything in my new house, including Chromecasts. There's enough going wrong with random software that adding a wireless link into the mix doesn't help.

And amusingly enough the more wired you use the better the remaining wireless connections are (as they don’t have to compete).
