Reading this article shows how far the knowledge is spreading and gradually becoming something difficult to tame no matter how the try. Despite the fact that a lot of people joining in those classes might be doing it for their own selfish reason and not necessarily to increase the body of knowledge, its still something that is worth happy about that in the many that are interested maybe few will eventually stay and be genuinely interested.
The majority of the schools here are in the United States which shows the amount of flexibility in the curriculum because over here, to alter the curriculum to accommodate for new area of knowledge like crypto, is an herculean task because of the bureaucratic impediments but I wish others academicians can see this as an opportunity to increase knowledge and solve problems.
