Well, why should drug dispensing machines be any saver than money dispensing machines...
One way to look at the problem is to conclude that the free market is not able to provide sustainable long-term solutions.
So what will it be - a medicinal-industrial complex akin to the military-industrial complex? A handful of companies that control the market - but are increasingly unable to deliver anything useful (Exhibit A: The F-35 desaster)?
Or a cluster of manufacturers attached to universities to combine R&D and actually building stuff, all run by the state in order to make sure they are still operating in a couple of decades?
