The quote from Walter Isaacson's biography of Steve Jobs emphasizes the idea that true expertise and knowledge do not require flashy presentations to convey their message. It suggests that individuals with genuine understanding can communicate effectively without relying on tools like PowerPoint. This challenges the notion that visual aids are essential for conveying important information.

Jobs himself was known for his charismatic and effective communication style, often engaging directly with his audience. The quote reflects his belief in the power of direct dialogue over polished slides, illustrating a deeper principle that authenticity and clarity can be more impactful than elaborate presentations.
