Somewhere in that 20-year period, I would assume that there will be some basically new approach that will begin to cut into it, but it's got a long time.
Well, it's very dangerous to project, but it's clear that the existing technology has some more years to go.
It's true that the original idea was mine, but what you see today is the work of probably tens of thousands of the world's best engineers, all concentrating on improving the product, reducing the cost, things of that sort.
I'm doing a little consulting. I'm somewhat retired, still a director of a company or two.
