Recursive nostalgia

I was thinking about the 1970s recently, and in particular about how it felt like science was about to send us into a new lifestyle. There were shows like "Space 1999" and comics like "2000AD" which promised us space exploration and jet-packs in only thirty years time. Thinking about that, I felt a bit sad that such promise hadn’t been fulfilled.

Then I realised I was being nostalgic for a time when people longed for the future.
