I think the push-back is that it's not black and white. If we end up in a situation where somehow we get 10x the number of ventilators and staffing becomes the limiting factor, you can bet that hospitals will get creative on how to operate them. You're right, pulling in people off the street is not the place to start (even 1337 Javascript coders). I would think you would start with trained physicians from other disciplines, PA's, NP's, RN's.
