Its just us humans standardising on a way of doing things, it wont be the best for every situation (no standard ever is) but it's at least a way of giving direction.
Its only been standardised because it what works for society, and only if it stops working for society will we change it.
I do suspect there might be a change to our fundamental thinking in the pipeline, look at the suicide rates for under 25's (or millenials if you want to be a condescending ***** about it), a generation that's had it the best of any generation before them in terms of technology, education, leisure activities etc is suddenly finding modern life all too much. There's something wrong with the system and it'll need to change.
I suspect it's being caused by the advent of media being blasted into us from every direction all at once from the constant clickbait headlines through to facebook and the expectation you need to be a happy interesting fun individual who's always available to respond all of the time.
