The idea that some bubbles might be “good” is not new. History is filled with episodes in which investors’ collective mania produced ruin for many — but also left behind the bones of modern prosperity.
Economists sometimes call these cycles “productive bubbles” — periods when exuberance finances the future more quickly than sober capital ever would. But they also serve as reminders that innovation does not immunize markets from arithmetic. The line between progress and peril is only clear in hindsight.
For financial planners and investors, the lesson is timeless. Booms born of technological promise often end with disappointment, but they can also redefine the economic landscape. The challenge is to capture the lasting value without mistaking speculation for strategy — to own the rails, not the dreams that built them.
