Well-Behaved Bubbles Often Make History

Hobart treats a bubble as a collective, not fully rational conviction about the future, and argues that this kind of belief often lies behind major achievements. He follows the pattern through Apple's iPhone work, persecuted political movements, and marriage, then turns to how financial records and investment memos show what investors expected. He ends with advice for companies on surviving bubbles, favoring quiet work on surprising products over loud announcements.

• Criticism of bubbles is common, but the right bubble at the right time can produce lasting benefits.
• Ambitious projects like the iPhone required teams to stay convinced of an outcome the evidence did not yet support.
• Shared commitment, whether in politics or marriage, works as a coordinating signal that others take plans seriously.
• Investment memos act like science fiction meant to come true, recording assumptions about the future.
• Bubbles can leave useful byproducts, such as cheap fiber from the telecom boom of the 1990s.
• Companies can survive bubbles by keeping a public vision but quietly building products that surprise people later.

Hobart writes dense, allusive prose that moves quickly between finance, history, technology, and pop culture, often in parenthetical asides. Retyping him teaches compressed analytical sentences, unexpected analogies, and a dry, understated humor.
