Probably not. Elements of it have already made it (i.e. React, Redux), but pure FP has a learning difficulty curve that is too steep for enterprise software, meaning most of the apps out there. From my experience, companies don't mind increasing the number of engineers on a project but they almost never like to increase the sophistication of the code.
