This, I beg to differ. GPs would be happy to use their smartphone or the software version of this app on their computer for the initial diagnosis (GPs don't really do surgeries btw). I can see GPs using this app before they write a referral for chest x-ray film. However, this app can only but only complement the current gold-standard protocol, it can NOT replace it.

I agree with rest of your points. Unfortunately, there are many investors who don't have a very clear idea or experience about medicine, science or most importantly the best-practice policies encapsulating the overall process.
