Despite its young history, Computer Science Education has seen a number of "revolutions". Being a
veteran in the field, the author reflects on the many changes he has seen in computing and its teaching.
The intent of this personal collection is to point out that most revolutions came unforeseen and that
many of the new learning initiatives, despite high financial input, ultimately failed.
The author then considers the current revolution (MOOC, inverted lectures, peer instruction, game
design) and, based on the lessons learned earlier, argues why video recording is so successful. Given the
fact that this is the decade we lost print (papers, printed books, book shops, libraries), the author then
conjectures that the impact of the Internet will make this revolution different from previous ones in that
most of the changes are irreversible. As a consequence he warns against storming ahead blindly and
suggests to conserve - while it is still possible - valuable components of what might soon be called the
antebellum age of education.
