I think this is not properly accounting for the difference between something that&#x27;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.<p>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&#x27;s not a problem for Qi to be 90% done. And that&#x27;s a lot easier to accomplish by oneself.
