Earlier quoted context omitted.
The problem with the medical and biological fields is: you generally need expensive equipment. Also, you will need expensive certification. This is something that wasn't the case for software, so I guess this is also why this goldrush was so much different than anything else we've seen before.
Good point, but my medical friends' complaints tend to be about the software they have to use more than anything else. And on top of that there's a lack of software tools for a lot of things they do.
In my experience, it is very difficult to make money with scientific software in general, so I'm certainly not expecting a "goldrush" here.
