Elon Musk once told his Tesla employees that it is dumb to keep managers in between conversations. He believes that people should directly connect with the person they want to talk to. This seems to be the same reason why Musk does not like to have a personal assistant. Recently an excerpt from his biography by Walter Isaacson reveals that Elon Musk got rid of his personal assistant because he prefers to manage his things directly, especially like taking control of his calendar and deciding when and whom to meet.
