What's new is that they are using FP instead of C++ to deliver results quickly and more reliably.
These aren't the quants from the 90s that were Physics PhDs applying the latest and greatest in differential equations and whatnot. These are programmers who know how to make the complier do more work for them so they achieve results faster.
