Actually, I'm wondering what Haskell has to do with any of this at all.

You're comparing the size of the current incarnation of a fairly modern functional programming runtime with the capacity of computers that existed 10 years before the first incarnation was realised...

The only message I can take from that is that programs today are quite big. That's only really interesting from a nostalgic point of view, I don't see what relevance it has to the discussion of mutability?

Of course, I could have missed something obviously significant here...
