Hmm, have those predictions of life changing uses been borne out in places like South Korea, with actual superfast internet? (Not sarcasm, genuinely wondering)
I work with 3D imagery data, our customers need to upload gigabytes of data and models. Mining customers in certain regions of the US basically have 56k connections. America's infrastructure makes it impossible to do high tech, high bandwidth work. Maybe people only design and build low bandwidth applications because that's all our weak infrastructure can handle.
If we had better infrastructure, we would take advantage of it, I guarantee you.
