In Walter Isaacson's book "The Innovators: The Geniuses Who Invented the Future," the author explores the concept of visionary thinking and its potential pitfalls. He illustrates how a once clear vision can devolve into confusion and misguided interpretations, leading to ineffective leadership. This phenomenon highlights the importance of maintaining clarity and practicality in guiding teams and projects.

Isaacson argues that when leaders become too engrossed in their visionary ideas, they risk crossing into a realm of delusion, where their insights transform into hallucinations. This shift can undermine their effectiveness and disrupt the collaborative spirit necessary for innovation, illustrating that a successful vision requires grounding in reality.
