I also think “less than a dozen” is a clear underestimation but I am also convinced (and concerned) that Economics of Transformative AI remains a niche topic.
And yes, Acemoglu’s paper is probably not a root cause of this lack of interest, but a symptom of it. From what I observe, economists’ inner world models typically just don’t allow the possibility of any major disruption, only slow and gradual effects.
An update: eventually the journal Economic Modelling accepted and published the paper: The economics of p(doom): Scenarios of existential risk and economic growth in the age of transformative AI—ScienceDirect. Hooray :)
