If you could program the job skills and knowledge onto a human brain, why not a positronic one? All the non-creative jobs would just end up being automated.

I find it possible that they are, and that the work done by the non-elite is largely unused in practical applications, but they're still encouraged to do it for two reasons: (1) it gives them something to do, and (2) the competitions (Olympics) give a model for elite human performance that the upper-class technicians and academics then automate.

While it's not strictly answered as to why these competitions are called "Olympics", the general sense of sport is an activity from a previous time. We don't need archers to defend castles or hunt boars, or runners to carry messages at 8 miles per hour when we have cell phones, but there's something innate about the sports that makes us enjoy partaking and (for some) competing and spectating.

The activity of the other 99.999% isn't needed on the front lines, but it's important for keeping human skills and knowledge sharp and so the 0.001% (assuming that the reveal at the end is a reliable source, and it may or may not be) who can be original thinkers have some basis for what to improve and what behaviors the machines need to replicate.
