It's a problem I've spent a lot of time on, just not through the products marketed like temporal. I commented on the article because it's about program replay with checkpointing which is similar to what I worked with/mentioned. I didn't see the article mention idempotency anywhere, and you didn't in the original response to the guy who said it just sounded like a buzzword; atomic snapshotting with deterministic execution is literally how you make a program continuation an idempotent function! And the article is about solving the problem at the language runtime level so it doesn't even do that. So it would be reasonable to assume it is a buzzword if it does not have the essential property you mentioned and I was referring to. I was not even intending to disagree with you but just add what would make it less of a buzzword in this kind of case.
