Social change and technology change

> When we think about long-term change with the benefit of hindsight, the things we think are unfathomable are usually the technology – planes, cars, computers. But it is at least as likely that the things that time travellers would most struggle with are the shifts in social values, which are almost invisible to us because we swim in them constantly and adapt ourselves to them as they change.
