I find it absolutely, utterly, and completely implausible that the intelligence community just now started to research this possibility. It's been an obvious idea for decades now, and the tech has visibly obviously been roughly up to the task for decades as well. The last couple of years may have given an incremental improvement but it is completely implausible to me that they don't have workable solutions to this already. It's not like the system is useless to them until it 100% fingers exactly one person.
This sort of writing style analysis has absolutely been used to ID pseudonymous / anonymous individuals online for over a decade.
The new twist seems to be using "AI" instead of more traditional algorithms. Personally, I would expect that to make the process more error-prone, but it makes sense to try.
