James Fallows has linked a fascinating series of 1910 French prints that depicted the future they imagined for the year 2000. Matt Yglesias is particularly struck by one showing people heating their homes with radium, noting that France is in fact the world leader in nuclear energy.
What strikes me is the clothing--none of the prints envisions anyone wearing anything except, well, basically what people wore then. I don't know whether the difference is time, or culture--but if these prints had been made in 1930s America, they would certainly have depicted people in futuristic space suits, not plaid suits and fedoras. Why did people in 1910 assume nothing would change? They'd seen a pretty damn large revolution in male fashion at the turn of the 19th century, so why think that it couldn't happen again?
