From the article:

The bad news is that the 6 GHz wireless spectrum uses shorter wavelengths. Short wavelengths are great for fast data transfers at close range, So, they're great for connecting to your Wi-Fi 7-enabled HDTV a few feet away from your router

With a range that short, you're not going to be doing much roaming around. It obviously has some use cases, but unless you need to be streaming data it doesn't make a lot of sense.

The example we are discussing in this thread is transferring data off of a high res/high performance camera. For many situations this can be done after filming is completed, in which case a cord still makes a lot more sense. Hence my joke.

For live broadcasting it could be useful, but the range still seems quite limiting.
