> is because industry is slow to assimilate many state-of-the-art ideas, sometimes by as much as 40 years
How convenient that the software industry is about 40 years old. So these ideas should "break through" this invisible arbitrary corporate waiting area into the limelight any day now, right?
They are breaking though. For instance, Python just got (a very limited form of) pattern matching. It has been A Good Idea since at least the 1970s. Garbage collection has been known since the 1950s but only became "mainstream" in Java.
