Recently had a throwaway thought while reading The Dawn of Everything.

The formation of cultural norms fundamentally sit on the idea of recollection of the distant past and not of that which has just happened in front of you.

Example: The reason for wearing ties is part of the western cultural code not because each person distinctly and has first-hand witnessed how it started, it's just being shaped by historical precedent.

So what happens, over time, to cultural norms when the recollection can be made in first-person, distinct ways? (Think the internet, VR)
