I am not a computer scientist but I acknowledge Dijkstra is an honored name in that field. Yet for his shots against academia and industry, he signed it 'prof. dr.' and 'Burroughs Fellow.'

To put it charitably, Dijkstra was unusually sure that his opinions were objectively correct.

"I don't know how many of you have ever met Dijkstra, but you probably know that arrogance in computer science is measured in nano-Dijkstras." -Alan Kay
