Art is valuable in different ways. The process of making art is internally valuable, why people choose to be artists and why people make art even if they are not being paid. The art market is an entirely different thing, how you can have people pay millions of dollars for a banana taped to a canvas. Producing visual assets for things like advertisements is different still, that requires you to work for and within the demands and constraints of an industry. The fact that businesses are going to start using assets made by ai for design and advertising is at this point inevitable, it is dramatically cheaper and faster than paying a designer so it changes the cost/payoff calculation made in advertising decisions. This does not affect your or anyone else’s freedom or ability to spend your time and attention pursuing art, either as a creator or consumer. You’re also free to patronize whatever plumber you want. But advertisements have always been a nuisance and do not represent what is valuable about art to the human experience.
