Another error:

The translation of "We mogen niet uit nonchalance fouten in een programma aanbrengen. Dat moeten we systematisch en met zorg doen." is not "We should not introduce errors through sloppiness, but systematically keep them out", but "We should not introduce errors through sploppiness, but systematically and with care.". So it's nearly the opposite.

Dijkstra did not introduce errors systematically and with care. He did, by structuring his solutions using appropriate levels of abstraction, keep them out.

Compare the T.H.E. OS with Brooks' et al IBM BOS. Brooks' team created lots of debugging practice. 40,000 bugs and climbing when I read about it... all those years ago.
