Tangent time:

A pound of feathers has a slightly higher mass than a pound of bricks, as the feathers are made of keratin, which has a slightly lower density, and thus displace more air which lowers the weight.

Even the Million Pound Deadweight Machine run by NIST has to take into account the air pressure and resultant buoyancy that results.[1]

That would be another misunderstanding the AI could have because many people find reasoning between mass and weight difficult. You could change the riddle slightly by asking "which has more mass" and the average person and their AI would fall in the same trap.

Unless people have the false belief that the measurement is done on a planet without atmosphere.
