As is usual for predictions of the sort  referenced by the editoral, here we see nothing but wild and inaccurate prediction which gives no grounds at all for us to believe it.  IT departments will not disappear any time soon.   They will change radically, and probably get used to taking up more software that they didn't write themselves, but they won't disppear.  Accounts departments didn't disappear as a result of Lots 1-2-3, they survived the relese of Borland Quattro Pro, and they were not abolished because the CEO could do it himself with Excel.
