IMHO, it's happening because we the humans optimize for proxy metrics which once were good as a proxy to the real thing but with the computer age they turned into shallow goals that end up destroying the real thing as the optimisation became too robust. Removing the human element from the machinery creates a fatigue on the remaining parts and the consumers. All jobs have become horrible, even if the productivity increases the optimisations end up destroying the workforce and this started eating into the society because no one is happy with their job and life. Seamen no longer can see the world through their sailing career because the stays at the ports are too short, a person can't have a simple job and a simple life because the simple job is optimised into exhaustion.
