The wrong question ...
Some medical AI having/not-having some medical data of mine is not the really important question; the real one is where else does that AI pass that data, probably without my agreement and out of scope of what the NHS trust thought it was agreeing to.
I don't want to find: myself getting spam for hypertension pills; or my mortgage rate going up; or being denied a job; or ... We all know that private data will end up in all sorts of places not envisaged, there will be flimsy excuses invented to give a veneer of justification - but the real reason will be some organisation's profit at my expense.
