<!DOCTYPE html><html><head><title></title></head><body><div style="font-family:Arial;">long, long ago, I took my MS in comp sci in AI. Expert Systems, by the 1990s, were the darling tech. It was asserted, with exquisite confidence, that ES would soon replace Doctors, Engineers, many Scientists, almost every job. (I once built an ES to cook Campbell's Tomato Soup, replacing a retiring human "cook?'.)</div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Feigenbaum, one of a multitude, predicted that any company not using ES would be out of business before the end of the 20th century. Programs like MYCIN ran circles around human medical diagnosticians. ES traders outperformed humans with the stock market. "Success stories" were rampant and gained lots of headlines.</div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">By 2000, ES had almost entirely disappeared, and today, few, even in AI, know what they were, (not taught in most CS-AI curricula.) Turned out you could not capture and represent human expertise with a set, even a very large set, of production rules traversed by an inference engine. Also, it turned out it was impossible to find any kind of "universal' set of rules - different experts use different rules and pay attention to different data. No multi-expert ES was ever built. The closest to realize that goal was an ES for analyzing leaks in dams to determine severity and need to fix.</div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Plus, experts lie. For example, I did Protocol Analysis (expert says aloud what is being done/thought, and you observe) one time with an expert human diagnostician. One time he walked into a room in the hospital and he stated, "first I look at the chart, notice a fever of 100 and the nurses observation of a rash. I examine the patient and notice the red spots with the peculiar structure indicative of measles, confirm the patients temperature, ask about exposure vectors, and then write down my diagnosis on the chart along with a recommended treatment." What I observed: he walked into the room took an audible sniff, wrote measles on the chart and walked out of the room. Asked later to explain the difference he said, "Oh, that is what we were taught to do in med school. Wasn't necessary because I read an article on the train coming to work about a huge outbreak of measles, detected the obvious scent of the disease, very distinctive odor, and did the diagnosis and treatment plan directly."</div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">I see a lot of parallels to the AI hysteria today and am not surprised by the rapidly increasing articles and studies that are highly critical and, essentially, claiming the emperor has no clothes.</div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">davew</div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;"><br></div><div>On Fri, Jun 20, 2025, at 2:32 PM, Pieter Steenekamp wrote:</div><blockquote type="cite" id="qt" style=""><div dir="ltr"><div>You're absolutely right — and thank you for calling me out!

Sounds simple — it’s just one cell — but it’s turning out to be a mammoth challenge. Meanwhile, a useful robot doesn’t need even one biological cell.

Some of this can be simulated by an AI. Take sarcasm as an example: humans use a lot of non-symbolic signals to detect sarcasm with a success rate of about 95%.
