Ethan Mollick(@emollick):The website for my book redone with Opus 5.5. The initial version (made with Opus 4.8) required a lot of work to make a distinctive-looking static site. Now Opus mostly did this alone. We have come a long way from generic ClaudeDesign in a very short time. https://t.co/Ti5jo6ksfI
