> Companies pick Java or .Net because hiring developers is easy, which business side loves

Instead of giving a counter-argument, I'll link to a parallel discussion thread concerning "hiring developers for programming language X is easy": https://news.ycombinator.com/item?id=47888298

> a lot of business development work is not rocket science. It's taking business logic and implementing in code.

In my experience (and I claim that I am rather sitting at the source), it is rather that developers who implement business logic are typically actively held back or prevented from inventing smart solution for the problems that the company has - even if these (very often) would be very helpful for the company.

In the area of implementation of business logic, thus the tall poppy syndrome [1] is very prevalent: you are very hinted not to think of innovative solution, but to be a good worker bee. This is why in my opinion implementation of line-of-business applications is frowned upon by many good programmers, and not because the questions that you are involved with are "boring" (they are not!).

Jane Street is always a bad example since they are working on niche problems that few people experience.

Sure, Tall Poppy happens because A) It's human nature and B) Companies don't want unusual poppy size, they want same size so when it's time to harvest some of them, they can just quickly cut.
