The dot-com crash proves that internet businesses are fundamentally unsustainable. The internet may be a passing economic phenomenon.

The NASDAQ peaked on March 10, 2000 at 5,048. By October 2002, it had fallen to 1,114, a 78 percent collapse over thirty months. Hundreds of companies with "e-" or ".com" in their names had vaporized. Pets.com, Webvan, Boo.com, Kozmo.com, companies with billions in market capitalization and no plausible path to profitability had simply ceased to exist. For anyone graduating into this wreckage, the lesson seemed obvious: the internet had been a speculative bubble, and the bubble had burst.

The lesson was half right. The speculative excess was real. Companies had raised money on the theory that market share mattered more than revenue, that any internet-adjacent business would eventually find a monetization model, that traditional metrics of business viability didn't apply to the new economy. These assumptions were wrong, and the correction was brutal and necessary.

But the correction eliminated the overvalued companies, not the internet itself. Amazon lost 95 percent of its stock value between 1999 and 2001, from $107 to $5.51 per share. It did not close. Google had its IPO in 2004. The underlying infrastructure, broadband penetration, server capacity, software tools, had been built during the boom and didn't disappear with the companies that had built it. The medium survived its speculators.

By 2010, Amazon, Google, and Apple had begun a run to become the most valuable companies in human history. By 2020, five of the ten largest companies by market capitalization were internet businesses. The dot-com crash was a correction in the financial valuation of internet companies, not a verdict on the internet's permanence. Graduating into the crash made the temporary and the permanent look identical. They weren't.
