The ability to recognize red objects is like the skill of riding a bicycle
I don’t think the question is about ability. Mary already has the ability to recognize red objects by using a light detector, for example. The question is that, when seeing red for the first time, it seems you’ve learned something new—i.e. what it feels like to see red.
The question boils down to whether subjective experiences are a form of knowledge.
