Demand for x86 processors isn't going away any time soon either, and they're only one of only two companies with a license to make them. AMD is currently strong on the x86 front, but their production is constrained by the wafer allocations they can get at TSMC while those wafers would be more profitably spent on making GPUs instead.
Amazon and Google are using increasing amounts of ARM. Apple pivoted from x86 to ARM for their computers. Enterprise Windows and computer games are the areas still most reliant on x86.
General Motors and General Electric are two large companies that slowly became much much less relevant. Intel's collapse if it comes will also have been a decade+ in the making.
