In any case, I recommend watching the 12-minute video in full before heading over to the discussion:
He saw what was most interesting about the new electronic things in California was going to be software. He didn't want to leave it to the engineers. He wanted the designers to do it. He called it "soft face": software interface. I thought that was a crazy name, but it grew into interaction design.
Last year, on my 60th birthday, he couldn't be here but he went into Central Park and dressed up as a penguin and made a video. He had a fascination with video as painting a picture of the future. I think he saw the designer's role as painting a picture of the future, which is so inherently positive. You have to be positive if you're all about the future.
