Sorry, but I don't agree. Really great software never ages. Like math: if it's correct, it never ages. Period. If it does age, it means it was not well engineered from the very beginning.

    «10 y.o. technologies are history. 10 y.o. software without major upgrades is dead. While 10 y.o. cars are quite good and decent.»

What about the Internet? What about LISP? What about UNIX? I could name a thousand pieces of software that date back from the 70s and are today as powerful and "new" as they were back then.

If the web does age, and it does, that should give us some pointers on what's wrong with it.
