If I want to download a multi-hundred-gigabyte anything, I switch to my mobile and turn on it's Wi-Fi hotspot. It's a really noticable speed improvement, with the caveat that speed varies a lot according to location and time of day.

My phone, a mid-range Android from 3 years ago, usually downloads over 4G much faster than any of the wired or fibre networks I have access too, including the supposedly newly installed dual fibre links at work, or the "superfast broadband" zone at my local library. It's also much faster than the 4G router at home.

I've downloaded terabytes over my phone, including LLM weights, and my provider's "unlimited" data plan seems fine with it. (They say 3TB/month in the small print.)

For practical purposes I agree, but in principle, why not? Especially in places where land-based ISP choice is not abundant or have crap speeds.

For example, my only choice is Comcast's 1.2Gbps/25Mbps service. If I need faster upload I have to tether to my phone. And I rarely get anywhere near that full 1.2Gbps down.

And there are people in areas even less well served by traditional ISPs where their primary Internet connection is wireless.
