The Personal Computer revolution was made possible by economies of scale in industrial manufacturing of relatively simple components. Companies made money by selling widgets to as many people as possible.
By definition, AI is only made possible by advances in massive computation capacity, which is easier to achieve and improve with centralized models. This is always going to be the realm of Big Money.
In a way, AI epitomizes the shift from XX-century economics, based on manufacturing, to a XXI-century version based on extracting rent from networked digital subjects.
