Final Cut Pro is a thing people already use in their workflow, becoming more convenient for them. People have depended on this as part of their production-ready workflow for over 20+ years now, and FCP-folks seem to have a lot of trust in the application and related tooling, that Apple isn't going to leave or abandon Final Cut anytime soon.
Google's AI features are not something most of us use in our workflow, and are (arguably/debatably) not making anything more convenient for us. That's all in addition to it being Google, so there's a built-in assumption that no one can depend on any of this, because it might be discontinued at any point with little notice.
(I say this as someone who does not own an iPhone or Mac, and has been on Android for over a decade) -- I can see why Mac folks would be excited by the Mac announcement, and why some aren't that excited by Google right now.
