TD spending is completely out of control, some of which has been about attempting to catch up to TSMC but completely unsustainable as a Foundry.
If the issue for Intel is one of bureaucracy and delusions of past success, then TD is maybe the costliest example, and I'd expect any corporate streamlining to bring TD spending in line with TSMC.
The company needs a significant headcount reduction to scale down to the revenue it is able to achieve with x86, and that has to come from Foundry.
Product divisions have always had methodology for rationalizing headcount to products, and while there is room to do more, the full weight of further reductions and elimination of non-productive R&D falls squarely on TD.
