Not unnaturally, many elevators imbued with intelligence and precognition became terribly frustrated with the mindless business of going up and down, up and down, experimented briefly with the notion of going sideways, as a sort of existential protest, demanded participation in the decision-making process and finally took to squatting in basements sulking. An impoverished hitch-hiker visiting any planets in the Sirius star system these days can pick up easy money working as a counsellor for neurotic elevators.
