Indeed, a phenomenal amount of money is at stake: OpenAI, which is still far from profitable, is currently worth more than Toyota, Coca-Cola, and Disney combined. This year, Big Tech plans to spend some $650 billion on the AI build-out—a sum that far exceeds the GDP of most countries. Investors are banking that AI will spur a productivity boom and deliver unimaginable corporate profits, but that future could be far off. If the spending dries up first, the bubble could pop—perhaps dragging the rest of the economy down with it. Nonetheless, Silicon Valley thinks that the present mania will eventually pay back its returns through scientific discovery and economic growth. “Stop trying to make bubbles go away,” as the entrepreneur James Thomason recently wrote. “The benefits of innovation outweigh the costs of volatility.” In other words: Be grateful for the bubble.
