Unlike the dot-com era where capital built unused "dark fiber," today's AI funding boom is different. Every dollar spent on GPUs is immediately consumed due to insatiable demand. This prevents a supply overhang, making the "circular funding" model more sustainable for now.

The dot-com crash was fueled by massive overinvestment in infrastructure (dark fiber) with no corresponding demand. Today's AI boom is different: every dollar spent on GPUs has immediate, pent-up customer demand, making the investment cycle fundamentally more sound.
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.
The current AI infrastructure buildout, while massive, is fundamentally different from the dot-com bubble. It's financed by cash flows from highly profitable companies, not speculative debt. Crucially, demand is real and immediate; unlike the 'dark fiber' of the 90s, there are 'no dark GPUs' today.
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.
Unlike previous tech bubbles characterized by speculative oversupply, the current AI market is demand-driven. Every time a major player like OpenAI 3x-es its compute capacity, the new supply is immediately consumed. This sustained, unmet demand indicates real utility, not just speculative froth.
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 comparison of the AI hardware buildout to the dot-com "dark fiber" bubble is flawed because there are no "dark GPUs"—all compute is being used. As hardware efficiency improves and token costs fall (Jevons paradox), it will unlock countless new AI applications, ensuring that demand continues to absorb all available supply.
Unlike the speculative overcapacity of the dot-com bubble's 'dark fiber' (unused internet cables), the current AI buildout shows immediate utilization. New AI data centers reportedly run at 100% capacity upon coming online, suggesting that massive infrastructure spending is meeting real, not just anticipated, demand.
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.
For the first time, investors can trace a direct line from dollars to outcomes. Capital invested in compute predictably enhances model capabilities due to scaling laws. This creates a powerful feedback loop where improved capabilities drive demand, justifying further investment.
