I see this as a serious and unnecessary problem affecting many products today. Perhaps smart phone integration is convenient or allows for interactions that aren't possible otherwise, but devices like smart phones are not reliable - they run out of batteries, they get lost or stolen, they change frequently, and they can be compromised. If anything of any consequence - especially a life-saving device - is dependent on a smart phone or other consumer-level product, that is a serious risk. Medical and other life-critical devices are held to very high standards with special development methodologies and testing criteria. Elsewhere, it's the wild West. Normally, general purpose software is poorly tested, riddled with known issues that were decided are not worth fixing, and has little to no security provisions. When a commercial-grade application controls a life-critical device, it defeats all of the effort put into ensuring the safety of the device itself. Safety is only as good as its weakest link.
