And AMD employed some of the most talented people in the area like Jim Keller. They totally can do it. Intel, too. Qualcomm is doing it with Orion and Qualcomm has less expertise and resources.
For the last 10 years, Qualcomm couldn't come close to Apple designed SoCs. Now they might come close after buying a team of ex-M1 designers.
It sounds ridiculous to say that AMD, Intel, and Qualcomm can do what Apple is doing. If they could, they'd be able to compete with Apple Silicon now. It's been 3 years. It's like saying AMD, Intel, Qualcomm can do what Nvidia is doing if they want to.
