And I answered that. The ultimate consumers will be a group of wealthy people who control the productive resources using AI and use them to pursue their personal goals. There will be some B2B exchanges between those people, and perhaps a smallish cadre of employees who's labor is still useful to the wealthy, but most commerce as we know it will grind to a halt because the vast majority workers' labor won't be valuable to those who could pay them.
