Pip, I have thought about your question ever since I saw it yesterday. Probably straying way out of the original subject matter, but, yes, I do wonder. They would no doubt be amazed by our technology. Imagine how magical a television would seem. Imagine how astonished you or I would have been 50 years ago to see an iPhone!
But would they choose our era? I think they would be lost in our modern world, horrified by our freeways (possibly altogether afraid of our high-speed cars, with good reason considering their ongoing death toll), outraged by the regimentation of modern working life, and appalled and disgusted by the amount of noise we live with. (Who on earth loves the noise of the ubiquitous leaf blower?) They would also probably be saddened by the excessive mobility of people today and the isolation that results for many, including many elderly.
On average, women would probably be more satisfied than men, as we now can own property, vote, work in any field we choose, control our child-bearing, wear pants, etc., and of course, as a consequence, men have lost of some of their hegemony.
I love my computer, and feel I was born to live in the Age of Information. I would not want to give up the simple conveniences of grocery stores, running water, etc. But studying history, my family's and history in general, also makes me aware of what we have lost. I would not choose to go back in time, but I really wonder how many of our ancestors would choose the lifestyle of today over what they had.
