It really won't, and there will be a ton of devices "jamming up" the airwaves. In most places the backhaul isn't fast enough for anyone to get any use for 320MHz channels beyond maybe very large LAN file transfers which are for some reason happening over WiFi?
Thankfully, there has been nothing new to use computers for since 2022. Definitely no new technology that involves downloading different 10+ Gib large files to test with, and users couldn't possibly conceive of a NAS, nevermind owning one because Netflix has never removed shows while people are watching them, breaking an assumed promise by users. ISP speeds are never ever going to improve either. Everyone knows that!
