The rapid surge in AI investments and valuations has sparked a serious debate in global tech circles about whether the current AI boom is sustainable — or just another bubble waiting to burst. Prominent leaders such as Sundar Pichai of Google, Jensen Huang of Nvidia, and Jeff Bezos of Amazon have weighed in — and while most insist AI is transformative and here to stay, there is growing nervousness about inflated valuations and debt-backed investments.
Critics point to several alarming signals: massive debt financing used to build AI infrastructure, circular deals where large companies invest in firms supplying them hardware and services, and a sharp mismatch between the scale of investment and current revenue from AI applications. One research note argues that commitments worth nearly US$1.4 trillion over the next eight years by AI firms may vastly outstrip near-term returns — a discrepancy that could trigger a widespread correction if revenues disappoint.
Some see history repeating itself. Skeptics draw parallels with the dot-com boom of the late 1990s — when excessive optimism, inflated valuations and speculative capital led to a crash. According to this view, many of today’s AI bets may fail, even though a few big winners will eventually emerge.
On the other hand, several analysts argue that AI differs fundamentally from past bubbles. Unlike many dot-com firms that lacked earnings, current AI-heavy companies are often already profitable incumbents reinvesting their cash flows into AI infrastructure. They suggest that AI’s value lies not just in consumer apps but in enterprise-level automation, workflow optimisation and integration across industries — areas where AI may deliver real, durable value.
They also argue that even if many AI startups fail, the underlying infrastructure — computing-capacity, data centres, chip designs, algorithms — could shape the foundation of a new digital economy, similar to how the internet boom ultimately delivered lasting value beyond the dot-com bust.
In short, the debate remains unresolved. The current wave of AI funding and excitement shows both the potential for a transformative technology era — and the warning signs associated with speculative manias. In the near term, much will depend on which firms can turn AI hype into real business models and sustainable earnings.
