The web will be a better place once everyone has 100mbps and servers have 10gbps. Sites like the verge can load in one second without caching.
Remember dailup back in the day? When a T1 would have been overkill for a single household? Look at those numbers from today's perspective: a T1 is only 1.5 Mbps, thats just 192 KBps.
My parents have only upgraded to "high speed" 512kbs in the last few years. My 80 year of Grandfather is still on dial up. I don't think expecting him to wait 5 minutes to load a Tweet is reasonable.
And even if you have large bandwidth, the latency that comes into play is another factor, not to mention folks opening 50 tabs which causes delays in opening and rendering a new one.
