I'm not universally pro-AI. I meticulously review every line of backend code, and still do hand edits. I review FE commits less carefully but still keep an eye on it to make sure AI doesn't go off the rails. But there's only so much trouble you can get into with CSS and the problems are the kind of bite-sized problems that LLMs excel at.
I don't think it matters at this point what you use for styling. If you like tailwind, the AIs use it just fine. If you like SASS, or raw CSS, the AIs are also just fine.
I'm not sure there's really a human job here anymore.
