Well, here's where we have to imagine the future. Because if some superbug shows up tomorrow and it travels through all these global trade routes and kills every living human, then globalization will have been very bad for human history, specifically by ending it. If climate change continues to accelerate and displaces billions of people and causes widespread famines and flooding, then we will remember this period of human history as short-sighted, self-indulgent, and tremendously destructive. On the other hand, if we discover an asteroid hurtling toward Earth and mobilize global industry and technology in such a way that we lose Bruce Willis but save the world, then globalization will be celebrated for millennia. I mean, assuming we have millennia and can convince Bruce Willis to go. In short, to understand the present, we have to imagine the future. That's the thing about history.
