> But the next near death experience came in the 2010s with the years-delayed move from 14nm to 10nm processes. This came kind of a joke in the industry and it's honestly still not clear to me what went wrong. Intel had previously migrated to smaller and smaller processes like clockwork.

I'd love to see a post-mortem. Intel's 14nm came out with Broadwell in 2014, and it was their desktop/server node for seven years, until Alder Lake in 2021. But they got stuck on the micro-arch as well. They shipped what was essentially the same Skylake core for five years from 2015 to 2020.
