I think people really have not yet grasped that society is changing so very fast. The discussion of AI is interesting. The attention is all focused on whether it will replace a lot of middle class jobs in banking and finance, law etc.
However, this talk occludes something else; which is means testing, benefits and your tax positions, access to public services could be easily managed by AI, and that digital access is the way this will happen. I agree that the current civil service is unlikely to facilitate means testing for the reason Serendipity Jane gave, but the idea that AI cannot facilitate this, that you cannot set a criteria for reviving benefits by having a bank account, and confirming your tax position is wrong. It will come. The cost saving is huge. You will not need human intervention to manage this on a large scale and in fact a bureaucratic mentality will embrace how easy and defensible it is legally, at least initially (see Post Office scandal for how insidious computer rightness is and how hard it is to get accountability).
I also think Labour will embrace AI in the benefits system. The cost savings now are potentially great. More scrutiny, cheaper, and less staff? Big tick.
