Hey, it would be great if I was an MD, great interacting with people (as all MDs are!), getting a positive vibe from their negative experiences and my positive effect on it, have actual job safety, gain respect and prestige in the eyes of the average person that no scientist in their messy shed of a non-glamorous lab would ever get, unless they win a Nobel prize.
Then it would also nice to be an actual doctor, not just a medical doctor.
Then it would also be great if I can be the new Elon Musk.
But it's not going to happen for me.It is just that the quickest and most straightforward way of becoming someone who does research in nano medicine won't involve getting an MD. You learn completely different things. That for applied nano medicine you need to work together with an MD, that's a different issue. Once you have something that works on paper, works in vitro, works in cell lines, works in test animals, then you go to the next step. But when you get to animal experimentation, the first person that came up with the whole fundamental idea is likely working on a new fundamental idea and only side-ways involved with the animal trial part.
As for entrepreneurship, that's a whole can of worms in itself. You don't even need to know any science or medicine. Just have the money and leadership to hire people that do.
