> This is like the fragmented 20TB hard disk (considers the magnetic upper limit) - even if you had a disk that size the seek times would mean months to take the data off.

The seek times don't matter if you want to read large chunks of data, it's the sustained read/write speeds that do, and it certainly won't take months. Also, I don't think we'll be using magnetic disks for much longer. 1 TB SSD's can be had for <$400 already.

That uplift is happening. South Korea, Japan, and several US cities can already do symmetric gigabit connections to homes at very affordable prices. The world will follow with time.
