The combined intellectual output of the field, across books, lectures, blog posts, verbal discussion in professional and personal capacities (many of them are friends or acquaintances), for about a decade. It’s just not possible to neatly condense that into a book recommendation, unfortunately. I can give you the flavor of it, at least, with this excerpt:

(Please excuse the archaic terminology of “robot” for LLM/agent, this was written in 2014 and LLMs weren’t invented until 3 years later)

    In the face of continuing debate about this point, I continue to think it obvious that robots will push humans out of work or at least drive down wages (which, in the existence of a minimum wage, pushes humans out of work).
    Once a robot can do everything an IQ 80 human can do, only better and cheaper, there will be no reason to employ IQ 80 humans. Once a robot can do everything an IQ 120 human can do, only better and cheaper, there will be no reason to employ IQ 120 humans. Once a robot can do everything an IQ 180 human can do, only better and cheaper, there will be no reason to employ humans at all, in the unlikely scenario that there are any left by that point.
