There was a time, not too long ago where electronic products had long lifecycles. When I was a young pup, my manager told me a story about when he first started work. He was hired in the 1950's and his first project was an electronic multiplier for a business machine. Vacuum tube electronics. The product worked well, but the company put it on the shelf for 10 years. In the early 1960's the company pulled it off the shelf and sold it for over 10 years. We are headed in the same direction with IC's. The Intel I-19 and the Ryzen 17000 may have 20 year lifetimes. There will still be a place for exotic high end machines, but their use will be limited. Intel's tic-toc might still happen, with a new rev every 5 years.
