I'm expecting stories to come out at some point in the future of dysfunction that's preventing Intel from simply implementing similar processes as their competitors. And yes I understand the competitors probably have trade secrets but they've been at least a step behind in process for so long now. 14nm when others had 7nm and just starting 7nm when others have 5nm. Hell there's already some 3nm TSMC stuff coming. The whole ++++++++ debacle was ridiculous.
At this point there has to be some major dysfunction. Are there senior people there with pet projects and adamant viewpoints that can't change? I'm expecting something along the lines of an execs insisting that cobalt conductors and liquid pellicles are the only way despite competitors kicking their ass by doing it differently. And if there are such stories to be told I'm rather shocked that no one at Intel's addressing the issues.
There's probably a book to be written here, similar to the stories told about Atari and Apple dysfunctions back in the day.
As for specifics I doubt we'll get many. Chip manufacturing is famously super-secretive and has a culture of not discussing the details - even for old process nodes.
