Hiring people to use knowledge is very expensive.
Our sapiens, as automated knowledge workers, will perform many of these same jobs for pennies per hour, 24/7, with their capability and utility increasing over time.
Consider just how much general intelligence beyond being able to talk to customers to determine their needs, wants and desires, is actually required of the people currently employed in the first tier of knowledge worker jobs such as bank tellers, receptionists or call centers? Consider also that people tend to find these jobs boring; they require a level of focus, attention to detail, and memory that humans find challenging (but sapiens will not).
When combined with specialist knowledge model extensions, the number of jobs that sapiens can perform as well or better than people will increase dramatically and move up into the professions. As modelled intelligence is interfaced to synergistic narrow AI techniques such as those for image recognition, auditory discriminatory and machine motor control, sapiens enhanced robots will perform more and more of the jobs that humans would rather not do.
