Recurrent thoughts in cultural history are the belief that there was a golden age1 long ago, and since then humanity has been in decline. The saying about "good old days" is similar to phrase of golden age.
In the idea of golden age I feel the same logic error that the "time-arrow" interpretation causes in physics. In physics the entropy law describes closed systems and this systems move toward simplification and symmetries. This law is on a par with thought of time-arrow. I wrote about this in an article2 hence I do not want to outtalk. Golden age was not in past but it will be in future. In the same way the Universe is not under physical entropy law, because it is not closed system. Direction of changes point to emergence of more complex3 systems.

3 There is picture of universe in a very large scale which shows our universe with fibrous structure of the galaxies. This picture definitively proves global increase of complexity to me.
