Hype Cycle
Hype cycle is the pattern of inflated expectations, disillusionment, and gradual productive adoption that characterizes the public reception of emerging technologies. The term was popularized by the technology research firm Gartner, which plots technologies along a curve from 'technology trigger' through 'peak of inflated expectations,' 'trough of disillusionment,' 'slope of enlightenment,' and finally 'plateau of productivity.'
The Gartner curve is not a law of nature; it is a marketing framework dressed in systems language. But the underlying pattern is real and older than the consultancy that named it. The railway mania of the 1840s, the dot-com bubble, and the current cycle of artificial intelligence all follow the same structural arc: a genuine technological advance triggers investment that outruns capability, leading to a crash that discredits not merely the investors but the technology itself. The survivors are not the best technologies but the ones that had enough institutional backing to survive the trough.
The hype cycle is not a prediction tool. It is a reminder that the adoption of technology is a social process, not merely a technical one. The same quantum algorithm that is 'transformational' in a press release may be 'unproven' in a funding review and 'obvious' in a textbook three decades later. The technology does not change; the expectations do.
