"AI" seems like the latest example of the so-called "tech" industry's worship of the Pareto Principle. If "AI" answers are correct 80% of the time and incorrect 20% of the time, that's good enough to promote "AI" as worth something. Demos can be faked if necessary, as Google recently did.

Perhaps this is similar to the practice of "vaporware". Musk's Tesla is a recent example. Neverending promises, mixed results.
