@DarkestKale I use it when proofing, but usually with my own heavily modified dictionaries.
I mostly complain about this nonsense when I use Google Docs to submit copy to the many parts of the publishing industry that Google Workspace captured.
The thing is, it's so obviously aggregating common use, but that's literally the opposite of what's required. I'm sure you could plot a fascinating graph about idiomatic and linguistic evolution out of this.
But what's being innovated here is significantly less useful than any rules-based correction tool.
(And yeah, I'm also team "machine learning is an amazingly fun creative toy, please take it away from the venture capitalists immediately".)
