All that needed to be conveyed was that there are humans who cannot create new memories. That is enough to pose the philosophical question about these models having intelligence. Anything more is just adding an anecdote that isn't necessary.
lol, as if pointing at a wikipedia article (without any relevant discussion of the contents therein) is some kind of conversational excellence.
Or perhaps you were referring to the impact of the two in that the "sledgehammer" of "they can't make new memories" is a lot more effective than the tiny scalpel of "if you do a wikipedia search this is a single one of the relevant articles"
The extra information is that he is the canonical case which defined our clinical understanding of the condition. Not just a "single relevant article."
I pulled it up because I was familiar with this fact.
