Oblivion (2013) Perfectly explains how Ai and technology in general swallows and erases whole classes in society by alienating them from the very culture that sustains them. The work you do isn't simply a task but a perspective lens into reality .Once you loose your place in society , society looses a whole window into itself.
This will accelerate once Ai becomes more nuanced in its capability .
I don't believe people who say it will not achieve sentience . Sentience is not a necessary criteria for the effectiveness of a hammer. You just have to see a lot of nails and keep hammering eventually everything becomes flattened into a single smooth mirror reflecting the pounding hammer . We normally call this process standardization.
