Microbiologists have been growing microbes on agar plates for nearly 150 years, but agar’s discovery dates back to a happy accident in a mid-17th-century kitchen. Legend has it that on a cold winter day, a Japanese innkeeper cooked tokoroten soup, a Chinese agar seaweed recipe known in Japan for centuries. After the meal, the innkeeper discarded the leftovers outside and noticed the next morning that the sun had turned the defrosting jelly into a porous mass. Intrigued, the innkeeper was said to have boiled the substance again, reconstituting the jelly. Since this discovery, agar has become a staple in many Japanese desserts, from yokan to anmitsu.

Tech job openings are falling. Hiring rates broadly are weak. And layoffs across the economy recently hit their highest level since 2009—although Zandi makes the distinction AI’s weighing effect on the job market “is due to weaker hiring, not layoffs.” Meanwhile, the National Bureau of Economic Research reports over 80% of firms in recent surveys say there is no impact from AI on employment or productivity over the past three years—yet those same firms forecast AI will boost productivity by 1.4% over the next three years. That disconnect between falling hiring numbers and rising productivity is precisely what worries Zandi and why he considers this a watershed Cortés moment.
