> In almost all cases the total amount of creation increases because the technology lowered costs

But this doesn't lower the cost of learning and writing CSS, it just scoops up some of it and offers that cheaply, and even that only because it's offered below cost. If anything I'd say it increases the cost, because now you don't get paid to get and be good at what an LLM is supposedly good enough at, and have less free time to do it anyway. You may not even have a computer because your current one broke and you can't afford a new one.
