I'll add in an aside to this, which is not only are there fake knitting podcasts there are fake knitting and crochet patterns, which is a problem because people get a substantial way through making them only to discover that they don't work. In some cases the giveaway is that the supposed final image isn't physically possible, like the images in this article, but the fakers can use a real stolen image and just spam a pattern underneath it.
So: what is the knitting that is real? It has to be the use of your hands, needles, and yarn to produce a physical object, right?
The podcasts work towards something else. The identity of "being a knitter". This is a form of "hobby" that was already not unusual, that of discussing a thing without ever bothering to actually do it. Photographers are especially bad at this: too many lenses, not enough photographs. They've also got comprehensively run over by AI, because you can just generate the photographs now. Same for "authors".
But ultimately all these pleasant sensations aren't backed by a connection to the real. If you're going to talk about the history of knitting, shouldn't it be the real, evidenced history? As done by real (usually) women? Otherwise you're just knitting a pleasant fantasy for yourself.
The AI approach is "wireheading": the logical conclusion of all of that would be to find a means of inserting a wire in your head that provides constant pleasant sensations. Achieving happiness through a constant feed of generated images is less effective, but it's the same order of things.
