I don’t think the problem is moving the goalposts, but rather there are no actual goalposts. Advocates for this technology imply it can do anything either because they believe it will be true in the near future or they just want others to believe it for a wide range of reasons including to get rich of it. Therefore the general public has no real idea what the ideal use cases are for this technology in its current state so they keep asking it to do stuff it can’t do well. It is really no different than the blockchain in that regard.
