I don't see any reason to believe this is true, not in the slightest
Either it's fake, or Stroustrup is a poor developer and that reporter is an even worse interviewer. It definitely reads like someone attempting to write a shock piece, rather than an interviewer trying to get to the bottom of something, right down to the inclusion of the "hmmm" in the last few lines of the interview, something which would either have been glossed over in the transcript or included more often throughout.
Given that it's also appearing on a lot of humour sites since a decade ago (2001 is over a decade ago!
) and this followup
I'm leaning even more towards hoax.
And I'm doing quite alright, how's yourself?
