Those are good points, David ... especially about turbines, and software.
If you were asked to propose a modern machine as the "prototype" for mass production within the constraints of the present crisis (if indeed that was a viable proposition), which one would that be?

And ... do you think there is any mileage at all in using an NIPPV machine of the Respironics V60 type as an invasive ventilator (may be good for "weaning off")? See post #75051 above.
