Historical technology cycles suggest that the AI sector will almost certainly face a 'trough of disillusionment.' This occurs when massive capital expenditure fails to produce satisfactory short-term returns or adoption rates, leading to a market correction. The expert would be 'shocked' if this cycle avoided it.
While spending on AI infrastructure has exceeded expectations, the development and adoption of enterprise-level AI applications have significantly lagged. Progress is visible, but it's far behind where analysts predicted it would be, creating a disconnect between the foundational layer and end-user value.
A new risk is entering the AI capital stack: leverage. Entities are being created with high-debt financing (80% debt, 20% equity), creating 'leverage upon leverage.' This structure, combined with circular investments between major players, echoes the telecom bust of the late 90s and requires close monitoring.
Unlike the dot-com era funded by high-risk venture capital, the current AI boom is financed by deep-pocketed, profitable hyperscalers. Their low cost of capital and ability to absorb missteps make this cycle more tolerant of setbacks, potentially prolonging the investment phase before a shakeout.
This AI cycle is distinct from the dot-com bubble because its leaders generate massive free cash flow, buy back stock, and pay dividends. This financial strength contrasts sharply with the pre-revenue, unprofitable companies that fueled the 1999 market, suggesting a more stable, if exuberant, foundation.
