the beauty of what's happening today is that AI might produce slop on the first try, but you can also refactor just as easily too. "clean up all !important and optimize the code for speed", is just as easy of a prompt and it'll go off and do a fantastic job at that. that is what the OP was talking about in his article.
you don't have a job because you're not adapting to this new world order quickly enough. i predict that there will be insane demand for porting existing applications off these over priced SASS contracts and building tailored products for businesses. as much as they are trying to convince people, you don't need a $5m/yr salesforce / servicenow contract when you understand the business model and can envision a better solution to the actual problem out of thin air.
i'm burning 500m+ tokens a day on a $200/mo subscription. it is creating 10000x more value for me. it is no longer how much you know HTML/CSS, it is how well you know how to get AI to do what you want it to do and the only way to develop that skill, is to do it.
