you say ai increases gdp growth, tax revenues and scientific innovations. then you say that ai is good.

that is not formally valid. in between those two you are smuggling the assumption that gdp growth, tax revenues and scientific innovations are good.

a) those metrics are poisoned, per Goodheart's law.

b) they are not good and human welfare will get worse as gdp, tax revenues and innovations grow.

i leave b for the reader to complete.

Which metrics are poisoned? Can you provide your arguments for why Good heart's law applies here and how and which metrics are bad measures? For b, can the writer at least provide their own thoughts or are they gonna leave it as exercise for some others to fill in?
