Turning a ship the size of Intel is a super power in it's own right. Especially one with such a large entrenched bureaucracy as Intel has.
Politics aside for a moment - we're seeing the death bellows of many large, entrenched bureaucracies right now with DOGE - the main difference is the fight is in full public view instead of behind closed doors. We can only imagine and speculate at the resistance Pat and others met while trying to change Intel's course.
The infamous Oscar Wilde quote is very applicable: "The bureaucracy is expanding to meet the needs of the expanding bureaucracy." - Ever large bureaucracy eventually exists largely to preserve itself.
This is why it is so incredibly difficult to reduce the size of a bureaucracy.
Every member is convinced the organization will fail tomorrow if they are let go today, and every member fights/resists any and all changes that threaten their bureaucracy and the status quo.
Best of luck to Tan - I truly hope he succeeds where many have failed at Intel.
AMD needs a healthy Intel to drive motivation and competition. The world will be watching.
