I think Intel killing Optane the way it did is premature it does make some sense in the long run. If CXL takes of the best parts of optane will live on in an industry wide standard. However I am having a hard time understanding the nuances between different CXL versions and implementations so it might end up as an example for the famous XKCD standards post. I was under the impression that optane was just starting to gain a bit more traction with major players like VMware acknowledging persistent memory through project capitola. Let's hope that Intel axe-ing Optane opens a door for industry supported pmem so that AMD systems can also benefit from it.
