Seems like a bit of a non sequitur. Nothing is guaranteed in life. That being said, you've got this backwards. The natural outcome of hiring a bunch of rails/python devs to fine tune a machine learning / translation / recommendation system is that you get hundreds of thousands of lines of code that run slowly AND don't work. The entire premise of "deep" learning is that the system is a black box - features are learned by the black box. And you typically use pre-rolled fast GPU implementations. Most importantly, very little domain specific knowledge is needed. In fact, getting that hand-engineered system is going to be more complex, more costly, and it's going to require people with more domain expertise.
