I heard similar arguments from a co-worker when talking about L4/QNX and OS research in general. "Nobody uses them / they don't work / where are they?" were the answers, all which have good replies if you google for 5 minutes.

IMHO, this happens when one has more opinion than knowledge. Pike, unfortunately, seems to suffer from a similar problem.
