>The reality is there is very little non-individualistic art (algorithmic, AI generated etc) that has much qualitative merit

Big opinions there. A large amount of art that you think comes from individual expression is often not. There are countless examples of artists that secretly used algorithmic processes. A great example is Vermeer: https://youtu.be/94pCNUu6qFY?si=M6UQ-XuHNtoj2-3a.

This is what I mean about how this individualistic philosophy of creativity actually just results in artistic gatekeeping and manipulation of the audience

It’s very common for artists to add on individual expression narratives at the end of the process just so they can market the art, and the reality is that the individualism was never there to begin with. It’s just manipulation and advertising, and it sucks because the success of advertising like this actually undermines the quality of the art world. Because audiences are so susceptible to advertising narratives, artists are forced to spend more time on advertising more than art

> Art for the most part has always been the expression of an individual, even art tightly bound to a cultural context.

This is also not true. This idea mostly comes from the Romantic period. Modern day versions of it are often really just referencing a single book from the 1930s called The Principles of Art by a guy named R.G. Collingwood. It’s a very recent way of seeing art. Historically, art was connected to religion, and therefore thought to be valuable because it was universal rather than individualistic and personal
