In 1601, an English sea captain did a controlled experiment to test whether lemon juice could prevent scurvy. He had four ships, three control and one experimental. The experimental group got three teaspoons of lemon juice a day while the control group received none. No one in the experimental group developed scurvy while 110 out of 278 in the control group died of scurvy. Nevertheless, citrus juice was not fully adopted to prevent scurvy until 1865.
"""
So lemon juice cut the mortality of scurvy in sailors by forty percentage points (!), from 40% to 0% (!!). And a mere 260 years after this was demonstrated, it achieved "traction". Do you think you might be jumping the gun a little here? History would suggest that even if programming in FP style prevented 100% of bugs from occuring, the best you could say about its eventual adoption would be "it's a crapshoot".
You're getting picked on here, and I'm going to do my best to add to the pile. From http://www.johndcook.com/blog/2008/03/25/innovation-ii/ --
