OK, true, but the question is: what is the minimum workplace effort of living people that must go into that organizing process? Let us measure it in hours for the sake of simpliticy.

In the extremes, 1 hour weekly is probably too little and 100 hours weekly is excessive. But given how almost the entire world has converged to approx. 40 on average, I'd be surprised if it was very different from 40.

Yes, this may change with robots and AI.
