laugh 1. software is a VERY new discipline. its also one of the most malleable. I doubt we'll ever stop seeing churn in this space. 2. we don't reinvent the how we build houses each year. you can safely ignore all this new fangled web things if you want. 3. churn is also domain specific. we've more or less stopped inventing drastically new APIs at the OS/system level. 4. software for UIs have never been great. we are still learning how to build them. most of the major players in UI software still exist, windows, java, macosx (cocoa?), QT, GTK, Enlightment, and HTML/CSS/javascript. finally software will continue to evolve as base layers add the ability for higher layers to do things differently. for example as CPU get more and more vector operations that can dramatically change how we write code. this churn is a positive not a negative on the industry.
