Well, it's not for lack of ambition. Their roadmap has them back on top with 18A in 2024. They also have plans to make a zettascale (yes zetta) supercomputer by 2027 +- 1 year. As much as intel is known for stifling progress, so have all (most/many?) encumbant monopolies. I hope they stay close enough to AMD, and vice versa, for healthy competition.
