Will firms that lease, sell, or do maintenance on robots sophisticated enough to truly approach the interchangeability of human labor, ever match human labor's ability to undersell themselves? Will they ever be as subsidized as human labor is by uncompensated care work and other expenses of social reproduction for which the employer takes no responsibility? How low will costs need to get on versatile humanoid robots for these firms to profitably compete with masses of desperate humans?
Capitalism cannot fully automate, and has no reason to. High-end robot firms are inherently harder to exploit than disorganized masses of hungry people.
