It's amazing the way a nice piece of tech can radically change the world over just a few years. Just decades ago, everything changed when we started putting computers in homes, and it changed again when we started putting them in pockets. But regardless of how revolutionary these innovations are, they're gone incredibly fast. It's a poignant observation, and who could have put it better than Steve Jobs.

In this recently released clip—put out to promote the Silicon Valley Historical Association's hour-long documentary based around the interview—Jobs ruminates on his legacy. Not how it will last though, but how it can't. Appreciate these leaps and bounds as they happen; your grandkids are going to be too busy with their holodecks to sit still for your rants about the iPad. [EverySteveJobsVideo via TUAW]
