San Francisco’s Financial District is like a dying coral reef: the structures remain but the color has faded and the dazzling fish dashing in and out have nearly vanished. Life as it used to be is different. Forever? I don't know. No one does. Things change, and rapidly. Or slowly. Predictions are almost always wrong. Sorry, you who confidently claim that workers will always want to roll out of bed and press their fingers against keyboards and phones, only drifting away for the occasional coffee, cocktail, or meal. This is still a time of anomalies, of unsettled business. Anything can happen.
