The person who painted that landscape has certainly been influenced by prior artists, is not the first person to have painted a landscape, and is creating a work directly derivative of nature itself. They didn’t appear from thin air a fully-formed human being and start painting the hills. The person filming a cat video has seen videos before. They know to hold their phone at a certain angle and in a certain orientation to get the view they want of the cat, and that also does not spring from a vacuum. These two artists are each the sum total of their own experiences, their training sets. The difference between inference and extrapolation in this context is only a matter of complexity.
