It seems the AI hype is quite justified, considering the massive progress that was made over the last ten years.

Edit: The Gartner diagram seems especially not suited for AI. Advanced AI is, in a clear sense, the final technology. The technology with the potential of creating new technology, including better versions of itself. Anything that is technologically achievable at all (consistent with the laws of physics) must be solvable with sufficiently advanced AI. Gartner, at best, applies to some forms of narrow AI.
