> I do not know the specific background of Mr Lee, but the thing I always tell myself is that you can teach programming to a microbiologist, but not microbiology to a programmer.
I don't know if microbiology is special in some sense, but I have witnessed several times during my career cases of programmers turned into domain experts(in Logistics for example).
Obviously you don't became an MD that way, if that was your point.
Yes, Wall Street (high finance) also has many people (traders & quants & risk controllers) who do not have financial engineering degrees, yet deeply understand the field as practitioners. Some common "alternative" degrees: economics, mathematics, physics, chemistry, microbiology, computer science/engineering. The previous generation was even less specialised -- many had liberal arts degrees!
