My own interest developed because I thought it was a fascinating subject and something I wanted to pursue.
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.
Today, people tend to credit me with having the original idea and made the first circuits.
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.
They were the largest semiconductor maker in the world up until about 1980. I'm not sure that that can be re-gained again, but their progress in the last few years has been very impressive.
