What was the dot-com bubble? What can it teach us about tech startups?
The dot-com bubble of the 1990s was the biggest bubble since the one ending in the Wall Street crash of 1929. The “lessons” of the dot-com dictate the way we think about tech today.
Continue reading for Thiel’s insights on the dot-com bubble and its lessons for entrepreneurs.
Lessons of the Dot-Com Bubble
Peter Thiel’s “contrarian question” is this: What significant truth have you discovered that nobody else believes? Thiel affirms that you can sometimes answer this question by working backward. First, ask what is the conventional wisdom that everyone believes. Then consider what the opposite of that would be. According to Thiel, the opposite of conventional wisdom is more likely to be true than the conventional wisdom. That said, he also emphasizes the importance of thinking for yourself rather than blindly following or opposing the crowd.
As a case study in the dangers of following conventional wisdom, Thiel recounts the dot-com bubble of the 1990s. Prior to that time, most people understood that businesses need to make money, but for a few years, it became fashionable to believe that publicity and traffic were more important than profits. Companies sustained large losses under the delusion that they were investing in their future success. The bubble broke circa 2000, when investors realized that this cycle of unending losses was untenable, and the lessons learned from the crash became part of conventional business wisdom.
But did we learn the right lessons from the dot-com bubble? Thiel argues that we didn’t. To understand the real lessons of the tech bubble for startups today, first we need to review the 1990s. Then we’ll analyze the bubble in more detail, and finally we’ll consider Thiel’s conclusions about the lessons from it that became part of conventional wisdom.
Historical Overview of the 1990s
We remember the 1990s mostly positively for the rise of the internet, but the 18-month dot-com bubble at the end occurred against a backdrop of growing financial problems in the US and globally.
The US economy had been in recession in the late 1980s, and economic recovery was sluggish in the early 1990s. At the same time, Americans had rising concerns about globalization, because American companies were outsourcing jobs to countries with lower labor costs and Japan was out-competing the US in the global semiconductor market.
And the US wasn’t the only country facing financial challenges in the 1990s. For example, in 1997, the economies of Thailand, Indonesia, and South Korea crashed due to massive debt and government corruption. And in 1998, Russia, also facing insurmountable debt, defaulted on its loans by devaluing its currency. The European economy was also struggling through its transition to universal currency. These crises contributed to a bleak global financial outlook.
