The model allows us to see some hypothetical outcomes of what happens when an AI has too much or too little confidence. But more importantly, it’s putting a spotlight on this issue. Especially in these nascent days of artificial intelligence, our algorithms need all the human guidance they can get. A lot of that is being accomplished through machine learning and all of us acting as guinea pigs while we use our devices. But machine learning isn’t great for everything. For quite a while, the top search result on Google for the question, “Did the Holocaust happen?” was a link to the white supremacist website Stormfront. Google eventually conceded that its algorithm wasn’t showing the best judgment and fixed the problem .
GREGORY PETSKO: For thousands of years, long before there was such a thing as a science of chemistry, people were fascinated by plants, because they knew that plants contained substances that could affect people. Coffee will keep you awake. Tobacco contains something that will calm your nerves. Foxglove contains an extract that'll affect your heart. And the whole goal of chemistry in the early part of the 20th century was to understand what these natural products were, to characterize their chemical structures, and figure out how to make them. This was called "natural products chemistry." It was the main branch of chemistry. And in 1929, Vienna, in Austria, was the seat of natural products chemistry. And that's why Percy Julian went there.
