I wonder if you'll change your view on this as you age. I'm 40. I've been through 2 divorces and 3 full-on professional careers (academics, music, and programming). I have a 17-year-old son. Although I can probably think out the evolution of my "software", it's really hard to think of my current releases as having a whole lot of backwards compatibility with that 0.0.1 version. If I had to give it a number, I'd say I'm somewhere around release 6.4.3. :D Personally (and this is just my conclusions, not one I expect other folks to come to), my views and strategies for working with the world are so removed from 25-year-old me that I have little problem saying that I am almost not the same person. Certainly, my "software" has so many revisions to essential functionality that it's hardly recognizable as the same collection of code: there is very little overlap between how I reasoned about things when I was 25 and now, and I feel like that's not just a matter of "data" aggregation. My conclusions is that the software isn't, in fact, the same. I feel like it's more that I've fundamentally revised the software on a number of levels to the point where there are so many essential differences the identity isn't even consistent.
