When AI (Artificial Intelligence) Goes Wrong...

The intelligence in AI is computational intelligence, and a better word could be Automated Intelligence. But when it comes to good judgment, AI is not smarter than the human brain that designed it. Many automated systems perform poorly, to the point that you are wondering if AI is an abbreviation for Artificial Innumeracy.

Critical systems - automated piloting, running a power plant - usually do well with AI and automation, as considerable testing is done before deploying these…
