I think this is not properly accounting for the difference between something that's 90% done, and something that is done. (Nothing is ever finished, of course, but you know what I mean.) As we all know, the difference between the two is not simply a gap of 10 percentage points. Far from it. Teams of people were required to write Haskell and Dr Whatshisname tossed off Qi by himself. OK, but people use Haskell, does anyone use Qi? If not, then it's not a problem for Qi to be 90% done. And that's a lot easier to accomplish by oneself.
