I don't think that is in principle problematic (unlike the social problem statements pointed out in the talk). A system which amplifies human resources by filling in for their common activities over time could use sophisticated tech drawing on the latest in NLP. The metric would be a ratio of the number of service requests they handle per day / the number of "trainers" (or whatever name given) compared to the median for a purely human endeavour where every service request is handled by a customer-visible human. In the Mechanical Turk analogy there is no such capability amplification happening.
