I don&#x27;t know much about this guy&#x27;s story, but I do remember from my time as a UC Berkeley undergrad that being a popular lecturer with the students is a sure fire way to get yourself unpopular with the tenured staff.<p>The brass professors at UC Berkeley seemed to be catty like that in all departments. They didn&#x27;t like it when some young gun became more popular than them for teaching the same topics that they&#x27;d been teaching for a generation. Which makes sense, popular professor sell things and get rich, and they way they saw it, they weren&#x27;t going to lose to some young upstart.
