A couple of years I had a nice talk about operating systems with a couple of pretty smart people (smarter than me, at least). I remember bringing up GNU Hurd and saying how sad I was it still wasn't there, yet. And somebody else said to look at it in a more positive way, because by the time it would be ready, at least I could run Perl 6 and Duke Nukem Forever on it.
So who knows, maybe we'll see Hurd 1.0 before, say, 2020. ;-)
I'm hopeful that Perl 6 will prove more endearing and long-lasting than Duke Nukem Forever, which was, frankly, a stinker (then again, we all grew up waiting for it, and Duke's 12 year old boy humor does not age gracefully).
