And what are we downloading? Is the cloud dead? Why do i need 15gbps on my phone? Is it made for consoles and their relentless 120gb patches?

    In the US we’ll do anything but build fiber with the billions we tossed at the telecom industry.

    For home use, all I can think of is wireless video. 15 GB/s is faster than the fastest DisplayPort or HDMI versions. It could handle any resolution and refresh rate currently in use without any compression. That would be useful for VR headsets since they need low latency.

    Yeah - that covers about 1/100000 users

    I'm pretty sure anyone using an HDMI cable could appreciate having no cables except power.

    On the flip side, if you still need a power cable anyway, it's usually way cheaper to bundle the media (and optionally control/network) signals into the same cable than using wireless. (Sidenote: Honestly it's kinda weird to me that we haven't seen hardly any of this in consumer spaces. The newer USB-C revisions could easily supply power, display, audio, and network to the average TV over one cable.)

    Now, with true wireless power (I'm thinking of this video in particular), that proposition can change dramatically.

    One example I've read, was to remotely drive autonomous vehicles, and feed back all data collected from cameras and sensors. I'm not a fan of it being used this way, but it would mostly serve that kind of purpose.

    For phones / portables, assuming it doesn't draw more power, it would mean shorter download times, which means less battery usage.

    "Assuming it doesn't draw more power" has got to be the problem here, right? I don't know much about wireless technology but from a purely physical stabdpoint, faster signals means higher frequencies, which means higher energies, which means more draw from the battery. Yes, shorter active time means less draw, but it's like that swiss cheese joke:

    Swiss cheese has holes.

    More cheese = more holes

    More holes = less cheese

    Therefore,

    More cheese = less cheese.

    Laptops have all but taken over from desktops for everything but AAA gaming. New houses are still built with zero Ethernet because "the internet is Wi-Fi right?"

    People are using their laptops to edit video off of a NAS, MacBooks can run 100 GB LLMs. Heck even non-AAA games are many gigabytes.

    More bandwidth available for users means more people can do more things on the internet and at a higher quality.

    If cell phone speeds are high enough, then we should be able to transition from wired internet which is not available to a lot of people to only using cell networks.

    Already in my neighborhood most people use their phones for internet because there is no wired internet available.

    It's also not going to be 15gbps per device.
