I like background insight stories like this. GN also did a similar deep dive with AMD on their campus too, and it was pretty cool learning some of the stories behind the impressive revival of AMD and some of the tools they needed to debug their prototypes.

Can this disruptive text be any more disruptive?

I'm an engineer, and have worked on CPU chips. People unfamiliar with the field often don't realize how challenging an engineering endeavor it can be. While simulation tool are excellent, they're both not entirely accurate, and it's also difficult to incorporate everything in a real system into the simulation. As a result, it's actually extremely common to have initial sample chips not function correctly, and need revision. Tools exist to modify sample chips, in order to experiment and try out different modifications to fix a problem (e.g. altering the metal layers with a focused ion beam).
