Their current foundries can't just make other chips, and they certainly can't make GPUs for AI (TSMC make Intel GPUs). They are making a new foundry in Ohio, but in Intel's current state and comments they've made to the market it's not guaranteed the foundry will be built.
Intel might make it out of the hole, but it's going to get worse before it gets better. At their current trajectory their is not valid reason for the company to have 100,000 employees. I expect the recent layoffs are the first of a few.
