This author has an unusual view on what constitutes his job. In my area, bioinformatics and life sciences, it is taken for granted that a professor or PI (principal investigator) will be performing very few or no experiments personally.
Becoming a PI is a devil's bargain: you get more resources and personnel to tackle the questions that interest you, but in exchange, you largely give up the ability to directly do research yourself. The research gets done, but the actual code is written or experiments performed by grad students and postdocs. The PI has two main tasks: 1) getting grants, and 2) deciding on the goals and methods of the research.
Many PIs would argue that having a PI do experiments personally is actually a suboptimal use of time, like having Steven Spielberg meddle in minutiae of costume or set design instead of managing the big picture.
