I don't think he was denying that "most operating systems and web
servers have been developed in C/C++", but that _most_ "are very mission
and safety critical"; in particular, would many people claim that
Microsoft s/w should be used in such an environment?

Of course there are C-based operating systems used in
mission/safety-critical systems, with the safety case supported by their
track record; but few if any HTTP servers are safety-critical (unless a
hospital has NO back-up sytem perhaps)
