Hi Freek, The first sentence at http://www-unix.mcs.anl.gov/qed/ is:"The aim of the QED project is to build a single, distributed, computerized repository that rigorously represents all important, established mathematical knowledge."
I think this is a target of multiple projects today - one of them Mizar, but e.g. all the "semantic wiki for formal math" recent suggestions are also driven by this goal (and by the huge practical success of Wikipedia, showing that such things are really possible in a couple of years if started and coordinated well).
The other point is that no project is sofar nowhere near achieving the goal. I think that the "goal" should rather be defined as a process that gradually tries to involve as many mathematicians/students as possible, and continuously tries to make formalization easier and easier for newcomers. That is the other attractive and probably very productive thing about the original idea of Wiki: it is never "finished" and "stable", and tries to be very friendly to fresh solutions. I fear that without such supportive climate and humble awareness of the huge existing bottlenecks that are waiting to be solved, no project will succeed.
So I think that in some sense the world is still waiting for the proper effort towards implementation of QED. We know that it is possible, but it is both a technical problem, and a human resource management problem. Especially solving the latter is in my opinion the crucial thing. The only way how a "technical solution" could be more important than the "human solution" is if very good tools and AI are developed, which will practically turn the "normal" mathematical papers into "formal" mathematical papers. E.g. TeX is an example of a technical solution that changed the world in a similar sense, and you never know where AI (for automated formalization of "normal" math) is :-).

Dear list members,
A few days ago I got the email copied below. And I don't
very well know what to say to it. Does anyone here have
a good answer to Arnold's query?
(I'm cross-posting this to a couple of mailing lists. So my
excuses for the duplication, but I'm really curious whether
there is anything interesting to say to this question.)

Subject: The QED Project
Freek,
are there still activities related to the QED Project
http://www-unix.mcs.anl.gov/qed/
I am contemplating writing a grant application for something going
in a similar direction, and would like to know about which people to
contact for possible collaboration.
What is your current assessment of what it takes to realize an
updated version of the QED project?
Best wishes,
Arnold
