While I think most agree with you, it's important to note there is more to networking than WAN access. Streaming 4k in your home network over WiFi sounds pretty awesome for security cameras and other self-hosted medias.
People who think the cameras will stop people from breaking in and stealing their shit, or the ones that think cops will somehow catch the bad guy and get their stuff back because they had a camera.
The thing you need is just a box that looks like it could be a camera. The most you can expect is that it is a minor deterrent and the footage will basically do nothing for you, so just pretend.
Mostly I end up just using one to see at a glance if, say, my wife is home (car is in the driveway) or to check out if that possum came back again last night.
Sure, though in my world none of my networking needs exceed the capabilities provided by the current WiFi generation, thus it remains unchanged. Nor will I see any benefit from it unless I conduct a thorough review and replacement of all impacted devices in my world to also accommodate WiFi 7, which I will not be doing.
With the number of people renting on the rise due to house prices in many countries around the world, running cables isn't an option for everyone (and even when it is, not everyone wants to actually do it).
Having more options available for people to move large amounts of data around their home is never a bad thing.
My upload speed is 10mbit/s. It's 2024, and this is ridiculous. I pay over $80 a month for this internet in one of the largest cities in the United States. I live in a very populated part of the city, too.
Yeah, it will help and it won't. If you're uploading through a typical cable internet connection, WiFi will almost never be the bottleneck. But if you're streaming 4k in a part of your house that doesn't have good coverage while other people use the same connection, it could make a difference.
I do a lot of streaming from my desktop to my TVs and I occasionally have bandwidth problems, so this could help that. And I have 300 up / 300 down fiber Internet, and in parts of my house I have problems getting anywhere close to that on WiFi. So WiFi 7 might help with those cases even if in the end your ISP is usually the bottleneck.
My ISP gives 1000mb down, currently no wifi 6 device can fully utilise that unless it's practically kissing the access point. So it will improve throughput over wifi 6. If your ISP doesn't deliver more than ~50mb, you might not notice
