I still think Intel missed the boat when they had the dominant process in focusing entirely on their own chips and not taking customers for third party fabbing. Samsung and especially TSMC have demonstrated conclusively that the real money is in producing chips for other companies. It might be lower margin, but the volume is undeniable and it keeps your company on its toes with node improvements.

Intel switched to a "service the stockholders before the customers" mode and they have never recovered.
