The now has been always preponderous over the past.

There are different ways to look at the issue.

* general assumption: the future is synonim of progress, so now is more relevant.

* general assumption: we know the past, so focus on the unknown aka the now

* fact: maintain the memories needs energy, and energy is a scarce resource. So societies forget its past to focus in the current issues to preserve themselves.
