Not sure that those systems are connected to the Internet. The software affected in the NHS was mainly in GP surgeries and admin offices to do with scheduling of procedures. Not directly life-threatening in the sense of a machine going wrong but indirectly damaging in the sense of procedures and consultations having to be cancelled, records not being available &c. Looking decades into future I'm wondering: Web applications + fairly basic clients Chromebook style for the scheduling/records stuff.
