If there is something that I have seen come to pass time and time again in technology, is that, the old becomes new again. You can literally make a fortune on identify the next big thing and then implement an old idea on top of it. Look at mobile, we started out with simple systems that took assembly or C (Newton, Palm) and graduated to Java and now we are seeing the latest platform move to web technologies. Take any facet of technology and you can draw a parallel to legacy technology.
