The current AI boom isn't a speculative demand bubble. Real companies are paying for and getting value from AI, creating a supply shortage, not an overhang. In the long term, the market's disruptive potential is actually undervalued.

Unlike the dot-com bubble's speculative fiber build-out which resulted in unused "dark fiber," today's AI infrastructure boom sees immediate utilization of every GPU. This signals that the massive investment is driven by tangible, present demand for AI computation, not future speculation.

While many fear an AI bubble, Ben Horowitz argues that current valuations are supported by fundamentals. Unlike past cycles, the customer adoption and revenue growth rates for AI companies are unparalleled. This historic demand justifies the rapid value creation, suggesting it's more than just speculative inflation.

The current AI moment is unique because demand outstrips supply so dramatically that even previous-generation chips and models remain valuable. They are perfectly suited for running smaller models for simpler, high-volume applications like voice transcription, creating a broad-based boom across the entire hardware and model stack.

Unlike the speculative "dark fiber" buildout of the dot-com bubble, today's AI infrastructure race is driven by real, immediate, and overwhelming demand. The problem isn't a lack of utilization for built capacity; it's a constant struggle to build supply fast enough to meet customer needs.

The current AI build-out is not a repeat of the dot-com bubble. Unlike startups valued on metrics like 'clicks,' today's tech giants are funding AI investment with hundreds of billions in existing revenue and cash flow. Furthermore, the demand for AI is already present and pulling supply forward, whereas the dot-com build-out was purely speculative.

Unlike the dot-com era's speculative infrastructure buildout for non-existent users, today's AI CapEx is driven by proven demand. Profitable giants like Microsoft and Google are scrambling to meet active workloads from billions of users, indicating a compute bottleneck, not a hype cycle.

Unlike the dot-com bubble's finite need for fiber optic cables, the demand for AI is infinite because it's about solving an endless stream of problems. This suggests the current infrastructure spending cycle is fundamentally different and more sustainable than previous tech booms.

The current AI infrastructure build-out avoids the dot-com bubble's waste. In 2000, 97% of telecom fiber was unused ('dark'). Today, all GPUs are actively utilized, and the largest investors (big tech) are seeing positive returns on their capital, indicating real demand and value creation.
