Not to continue an argument, but 2000 vs 2024; if you dropped someone from 2000 off today, they wouldn't be Shocked by anything. They might not like the general direction of stuff, but they wouldn't be shocked. Maybe we didn't have full on 'smart phones' but there was the keyboard phones, black berries, ect. Online shopping had started, although not super wide spread. We had widespread illegal immigration, I think that was roughly around the OJ Simpson trial (more or less). Any fool would have predicted China was on the rise. They would easily understand any of our vehicles, within a couple minutes. Go back 50 years, so, 1974, ill bet the Biggest thing they would be floored by is the internet/cell phones, but other than that, they wouldn't feel they where in an alien world. They would recognize cars, and maybe take a couple minutes to adjust to them, TVs, simple progression, computers, they would understand the concept of them, even if they'd never seen one.
Now, flip side, let's take a guy from 1865, and drop him off in 1915? Sure, he's probably seen a steam train a few times, and maybe even a telegraph, but now, in 1915, we have phones, cars, air planes, radio, maybe even electric in some homes, ect. The world map was radically changed, farm help now has to be Paid...,
We are Not in the Era of of fastest technology grow in human history.
Maybe this belongs in the 'world isn't really ending' thread.
