With respect to the quote:
the figure was calculated on the assumption that "100 percent of routine tasks and 10 percent of non-routine tasks can be automated."
Roger Needham, the Cambridge Computing professor used to say that "If there is an algorithm for it then it is administration, if there isn't them it is management". If those "100% of routine tasks" can be automated then it just needs very ordinary algorithmic computer programming to deal with them, not fancy pants AI. If the government had ever demonstrated the ability to get a finished, fit for purpose IT project past the finishing line then that is what they need to do. However, they can't, so a much more nebulous AI strategy, with nebulous goals will must better serve the career goals of civil servants, will be what is foisted on us, along with more failures in public services and of course more spending.
I suspect that government is like homelessness. If you just spend the money to put homeless people in houses in the long run it is a very cheap solution, much cheaper than all the indirect schemes to "tackle" homelessness. So spending a load of cash to pension off the 1/2 of the civil service who do nothing actively useful seems expensive, but would yield massive savings on a 5 year plus term.
