There is a comment on the r/slatestarcodex subreddit with supposedly true information about him (which I found googling 'who is gwern'), but it left me with even more questions.

> Gwern was the first patient to successfully complete a medical transition to the gender he was originally assigned at birth... his older brother died of a Nuvigil overdose in 2001... his (rather tasteful) neck tattoo of the modafinil molecule
The only concrete things we know about gwern are that he's a world-renowned breeder of Maine Coons and that he is the sole known survivor of a transverse cerebral bifurcation.
He does have a neck tattoo, but it's actually a QR code containing the minimal weights to label MNIST at 99% accuracy.
How do you know those things are true?
