This sounds more like a pitch for letting the MRI machine talk to the laptop than putting redundant chips in every device.
Do you want to put a rack of laptops inside the machine, waste several screens and keyboards? Log into every laptop with your AppleID before you can start your machine? It's such an inelegant solution.
Instead, the x86/Linux environment lets you put multiple mainboards in a machine, or you can choose a mainboard with more processors; it is a much more flexible solution in industrial settings.
This sounds like a huge security risk.
