It really is wild to have seen this happen over the last year. The days of traditional "design-to-code" FE work are completely over. I haven't written a line of HTML/CSS in months. If you are still doing this stuff by hand, you need to adapt fast. In conjunction with an agentic coding IDE and a few MCP tools, weeks worth of UI work are now done in hours to a higher level of quality and consistency with practically zero effort.
The only disadvantage to not using these tools would be that your current output is slower. As soon as your employer asks for more or you're looking for a new job, you can just turn on AI and be as fast as everyone who already uses it.
