It's not that Geonwoo lacked talent. We simply failed to recognize it. After all, ordinary people can never recognize a genius.
That's trying too hard to sound cool and failing.
The AI using "We" in the second sentence means it's including itself among the ordinary people that can never recognize a genius. But that removes the credibility of the third sentence, where the AI (an ordinary person) is recognizing a genius.
This would work if it was a narrator saying that "they" (the characters) failed to recognize it since "they" (the characters) are ordinary people, while the narrator is not.
(Yeah, you could probably make an argument about false positives and false negatives, but I still think this only really works if you have an external narrator.)
Or maybe I'm still half-asleep and not thinking straight...
