The realization came over me with full force that a good part of the remainder of my life was going to be spent in finding errors in my own programs.

-- Maurice Wilkes

What is so worthy mentioning on this obvious stament, describing fate likely shared by many thousand or milions of software developers worldwide ? Not much, only the date. According this book (which is a pretty good read btw),
Sir Maurice came to the sad realization mentioned above in the year 1949.

Just wondering - what have we learned since ?
