This is what makes me afraid for the future of software development. Even in this thread you see people saying they "don't write css and just let the ai do it." I don't think I could work for a company where the devs don't understand the language and just have chatgpt poop out blocks of code until it works, but we're starting to see exactly that now. And worse: they're proud of it. It's terrifying.
Most sites are just CRUD. Unless they are working on a site that requires creative styling, people just want to get it over with and work on the "real" problems.
