Engadget has posted a video clip of the first 15-minutes of the Steve Jobs and Bill Gates discussion from last night on stage at the D 2007 conference. I was completely enthralled, particularly listening to Bill talk about betting on the paradigm shift from character-cell to graphical user interfaces. That part of the conversation is a good reminder of just how young the software design field is yet, and of the kinds of things we were struggling with just a little more than 20 years ago. I highly recommend watching the clip.
Videos of the entire discussion are archived on the D conference site, although I haven't watched them all yet.
