I believe there are two different issues. The first is what is the maximum
possible number of articles (this is what I asked). For all practical
purposes (manpower we have, time until Wikipedia will collapce and cease to
exist, etc) we will only able to write a tiny part of them. This is why
media are discussing questions like whether English Wikipedia will ever
reach 5M articles. I think this is a much more complex issue which has to
do with the editor retention dynamics and general lifetime of internet
companies.
Yup, my bad, misread - sorry :)
