Thanks for the response. Yes, it is off topic in a sense but then it is critical as records management is not a "neutral" exercise.
I think computers are getting "smarter" but people are not. In many ways this adds to the confusion because of the permutations of interactions. The fallacy of recent cases 7/7 and yorkshire ripper is that somehow more computing power would have made those connections apparent. They were failures of imagination, a non computational skill, not of calculation or analysis.
