In April last year Bill Gates addressed a collection of students at Harvard for 24 minutes on the topic of where to devote your talents. It is well-known that Gates dropped out of Harvard in the mid 70’s to develop his fledgling software company. He was returning as a philanthropist on this occasion, armed with the following question “Are the brightest minds working on the most important problems?”. And clearly he does not think so, as it appears many of top minds in the US are going into sports, entertainment or finance. In fact, “The allocation of IQ to Wall Street is higher than it should be.” You can find the video of the talk here.
