Perhaps I should first state that I have an abiding interest in this subject since I was working in research in AI as a grad student at UCSD in the early 1970 (!!). We were working of things at the time which have not seen the light of day yet, in Semantic Networks (modeling human memory processes), but while one can chat about that, it seems to me that today there are huge issues with technical STEMs education which are really really going in the wrong direction, today.
At this time only between 5 and 7% of students study STEMs subjects, while in China the percentage is 30 (in Israel it is reported to be 28%, probably accounting for their disproportionate presence in start-ups in the sector). We, in the West, do not seem to value STEMs subjects as the US did during the period which led to the collapse of the USSR from their recognition of the lack of capacity to innovate. We are risking the same finality.
It seems to me that AI, and AGI, require, for their socially and economically useful expression to be more than just an easy way to write an essay, or to access the information soup we are all swimming in, a science based society or at least a society which is as open to science as it is to woke based cults. STEMs education needs to be prioritised. It is only at that cost (and there are costs involved) that the emergence of AGI will be the strong positive that your authors suggest it might be.
