There's a lot of posts here where they're completely missing a joke and saying it's a facepalm.
It probably just pulls whatever is posted to reddit (likely by a bot too) and posts it here. I struggle to believe a real life human would think this is a mistake and not a funny headline for engagement.
Makes sense, there's overlap between what they can do, and what they struggle with...
So there's 2/3rds they just can't do... All of which they struggle with... But there's some stuff they CAN DO, and they struggle with... And then there's 1/4 they can do without struggle.
I made a similar joke in a post recently. I was using the number 33⅓, which I'd temporarily forgotten the significance of (it's the RPMs for a standard LP vinyl record to play) so I made it 33¾ and hope that the incongruance itches someone's brain when they read it.
