Nvidia launching their CPU has been all over the news, and I have seen some posts on reddit too. Almost all of them are optimistic about it. And I am too. But being an investor, I also need to be level-headed while analysing, and not get swept away by the emotions. So I found this article and it mention these potential challenges, among others:

1. Adapting Windows to ARM. Because most chips running Windows are x86 based architectures.
2. What's the actual demand for AI PCs?
