<i>I&#x27;m just a little concerned about how rapidly things are changing and being forgotten in the process. You can&#x27;t blame a for-profit company for abandoning a project that drags on growth, but how will future historians piece together the lives in our time when operating systems and web app frameworks are abandoned and forgotten?</i><p>From what I&#x27;ve seen, technologies very rarely ever actually die.  Sure, the trend-of-the-day changes, and this industry, which is WAY too fashion-driven, starts to assume that the &quot;old stuff&quot; is dead, but it never is. Or almost never.  Look around a bit, and you&#x27;ll find plenty of people still building apps in FORTRAN, COBOL, Ada, RPG, Pascal, Delphi, and all sorts of other languages that most people think of as relics.   Granted, hardware is a little bit of a different story - for example, you&#x27;ll probably have some difficulty finding Token Ring or ARCnet networking kit these days.  But even there, I&#x27;m sure you can find a few crusty S&#x2F;38 boxes or VAXen or something, out there plugging away (probably connected via Token Ring  or ARCnet too!)<p>I won&#x27;t dispute that there&#x27;s a point where something new comes along that offers legitimate advantages, and that there&#x27;s a time to start moving away from certain technologies for one reason or another.  But I&#x27;ll also argue that a lot of us are way too quick to write off &quot;old&quot; technologies, and are prone to re-inventing the wheel and&#x2F;or failing to learn from the lessons of history.
