I saw the story from the Wirral and wasn't quite sure what to make of it. I'll be interested to know what you find if you can dig deeper. It looks like an excuse for cost-cutting and seems to be counter-intuitive in the sense that you would think you might need more specialised support to help someone through arranging their own budget. I had thought that the idea was something about that.
I don't see self-assessment as reason for less social workers as they will still need interpretating, but it has long been accepted that you don't need social workers to do care management.
With personalisation, there is still going to be a need for the same level of complex work - safeguarding adult inquiries, residential placements, complex care needs and shortly, deprivation of liberty assessments. I imagine that's the way social work with adults will go.
There's no reason a qualified social worker will be needed for managing care - but that's the way it is now too.
