It's not even remotely the same thing. It's a simple fact that there's nothing that requires gigabytes of data on a mobile device that can't be more easily done server side, unless it's real-time. And if it's real-time, the maximum amount of data is the maximum fidelity of data that the device can output (pixels times refresh rate plus lossless audio, either the device specs or its compute ability to drive the hardware). Right now, even if you max out your device's physical ability to output data into the real world, you're not coming close to maxing out your connection. The network isn't the bottleneck, and it's probably not even in the top three.

Investing in more bandwidth is a massive waste on the scale of billions of dollars when you consider that time and capital could be better spent improving existing coverage, lowering latency, and making the service more reliable. Creating a next gen standard that requires new hardware and new devices to support a use case that doesn't exist and can't materialize with today's devices is just silly.
