Exactly. Why am I supposed to take this seriously?
Believers in Superintelligenceism seem to assume that any problem in any field - physics, chemistry, biology, math, sociology, geometry, whatever - that hasn't already been proved impossible to be within the capabilities of an AGI, justified with a handwave and "oh, it's so super smart that it'll have it all figured out in an afternoon". This has more in common with religious concepts of omnipotent and omniscient gods than with anything any AI developers are working on today.
