This article is from 1998, the landscape was much different. Haskell had a handful of the language features it has today, and was lacking many of the innovations in its runtime and libraries.
Very true. I didn't mean this so much as a criticism of the article, but more of an addition to what the article was already saying. I think all the arguments addressed in it are pretty good, but it's not 100% up to date with the current FP world.
