Jobs's job was to look at stuff and see what he could sell, and to demand that employees invent more stuff to sell. Holmes' job was to invent stuff on demand. She tried (and failed) at a much harder job.
Jobs set the tasks, often demanding very specific inventions and advances - plug and play networking for NeXT, a vastly cheaper mouse mechanism, etc, etc. Only in hindsight can those marked advances be taken for granted. Often very correctly. He was an engineer, starting on the front line as she did, just not the best - I don't know that she was, either.
