It demonstrates the conventional wisdom for robots in the workplace - that robots will take only the "repetitive" and "dangerous" jobs.

Of course, as robots get more and more capable, there will be nothin that boxes them into these specific job categories. Economic pressure will demand that robots fill all jobs as soon as they can do so. So, robots will replace every truck driver, construction worker, restaurant emplyee, retail clerk, real estate agent, pilot, doctor, etc. in the not-so-distant futue. And thus we will arrive at the Robotic Nation.
