There is design that could be called art involved in the technical side of things; there's work that I've done that, at the time I could think, "This is the right way to do it. It powerfully feels correct." And I suppose that's similar to an artistic sense in some ways, where its not so much that I've measured everything and I've quantitatively shown that this is correct, but many times there is just the sense that the voice of experience of where its gone before, that something comes up, and sometimes is even a fairly abrupt thing where working something and then all of the sudden, "This is the right way to do it" and it becomes clear. And that's very rewarding. Its not that I just look at things and say, "Here are all the tasks, lets start slogging through them one after another" I do want to come up with- because the elegant design is something that allows you to do something two years ahead of where it should have been possible. And that is so much of what I've done in technology, where you don't need cleverness to do 3D games okay; the hardware is extraordinarily powerful and all you need to do is not do a horrible job and it still comes out today. But in the early days, it was what nobody thought was possible. And sure, you could have just waited, and eventually the hardware would have been there and everybody could've done it, but the fact that I helped make something possible two or three years earlier than it would have been done otherwise, that's still a good thing. If something's worth doing, it's worth doing earlier-its all that opportunity value.
