Stock market investors are pricing in rapid, significant productivity gains from AI to justify high valuations. This sets up a binary outcome: either investors are correct, leading to massive productivity growth that could disrupt the job market, or they are wrong, resulting in a painful stock market correction when those gains fail to materialize.

While investors now believe in AI's transformative power, it remains unclear who will profit most. Value could accrue to chip makers (NVIDIA), foundation models (OpenAI), or the application layer. This fundamental uncertainty is a primary driver of the significant volatility across the tech sector.

Today's massive AI company valuations are based on market sentiment ("vibes") and debt-fueled speculation, not fundamentals, just like the 1999 internet bubble. The market will likely crash when confidence breaks, long before AI's full potential is realized, wiping out many companies but creating immense wealth for those holding the survivors.

The rapid, unpredictable nature of AI makes corporate futures 'increasingly invisible.' This fundamental uncertainty calls into question all long-term valuations, sparking a debate on whether multiples for all businesses, not just tech, should be structurally lower, regardless of the macroeconomic environment.

The current AI boom isn't just another tech bubble; it's a "bubble with bigger variance." The potential for massive upswings is matched by the risk of equally significant downswings. Investors and founders must have an unusually high tolerance for risk and volatility to succeed.

In the early stages of a disruptive technology like AI, the market lacks concrete data, leading to a wide range of predictions. This uncertainty causes sentiment to swing dramatically from euphoria to panic based on narratives and thought pieces, as seen with recent software selloffs.

The startup landscape now operates under two different sets of rules. Non-AI companies face intense scrutiny on traditional business fundamentals like profitability. In contrast, AI companies exist in a parallel reality of 'irrational exuberance,' where compelling narratives justify sky-high valuations.

Initially, the market crowned OpenAI (via proxies Nvidia/Microsoft) the definitive AI leader. Now, with Google and Anthropic achieving comparable model performance, the market is re-evaluating. This volatility shows investors moving from a "one winner" thesis to a landscape where top AI models are becoming commoditized.

Despite a 70% drop in tech deal value and plummeting valuations, there is no objective data—like falling earnings or revenue—to justify the panic. The market freeze is a reaction to the *potential* for AI disruption, not current business failures, creating a crisis of confidence without a clear cause.
