This is a decent (not extraordinary) read except for three things: (1) I don't care for baseball, (2) this read more like a YA novel than I expected / than advertised. (3) The whole "like my mom used to say" trope followed by some trite, inane, and useless saying got old very quickly.
It's too bad though because the premise was smart: when AI takes over, a new form of segregation is created between the Netted (the still-necessary humans) and the Surplus (whose jobs no longer exist and are deemed unretrainable). To keep the social order in place, the Surplus are drugged and winnowed into mediocrity, constantly under the surveillance of the Autonet (nicknamed Aunt Nettie by the Surplus) while being told that they "always have a choice". AI totalitarianism in the context of climate changed (more hinted at than fully explored) should have made for a better story.
