The Gartner hype cycle is a useful tool for understanding how excitement about a new technology works. It’s also helpful to combine it with the idea of crossing the chasm.
The hype cycle implies all technologies will be useful but crossing the chasm reminds us they need adoption.
For example, the hype cycle would give you the impression that NFTs would one day hit the plateau of productivity. In reality, it never crossed the chasm because it didn’t solve any real problems well.
